I'm having trouble peeing?
THERE ARE A FEW POSSIBILITIES, IT SAYS YOU TAKE NO MEDICINE SO I ASSUME YOU ARE NOT ON ANYTHING THAT WOULD THIN YOUR BLOOD, LIKE ASPIRIN. WHEN YOU URINATE, AND YOU ARE DONE, DO YOU STILL FEEL THE NEED TO GO? IF SO, THIS IS LIKELY A UTI, AND YOU NEED ANTIBIOTICS. THAT SYMPTOM IS PRETTY SPECIFIC FOR A UTI, AND MANY PATIENTS WITH UTI'S WILL HAVE SOME BLOOD IN THE URINE, AS THE BLADDER CAN BECOME INFLAMED, AND SMALL CAPILLARIES IN THE MUCOSAL SURFACE MAY CRACK AND BLEED A LITTLE. IF YOU ARE HAVING BRIGHT RED BLEEDING WHEN URINATING, THEN I SUGGEST YOU SEE A UROLOGIST. OTHERWISE SEE YOUR PCP AND GET ANTIBIOTICS READ MORE
Bee sting on head causing facial swelling at bridge of nose into eyes?
TAKING SOME PRESCRIPTION STEROIDS WOULD HELP. I WOULD SAY THAT SHE SHOULD TAKE ZYRTEC 10MG- WHICH IS A ONCE A DAY ANTIHISTAMINE- AND BE SURE IT IS NOT ZYRTEC-D, AND TAKE IT DIFFERENT THAN THE BOTTLE SAYS. TAKE 2 IN THE MORNING AND 2 IN EVENING FOR A FEW DAYS, THEN AS THIS GETS BETTER DECREASE TO 1 TWICE A DAY FOR A FEW DAYS READ MORE
Is a dislocated knee an emergency?
IF IT IS TRULY A DISLOCATED KNEE THEN THERE MAY WELL BE A FRACTURE ALSO. MORE COMMONLY PEOPLE DISLOCATE THE KNEE CAP, OR PATELLA. THESE STILL OFTEN REQUIRE AN ER VISIT, BUT THEY ARE EASY TO REDUCE BACK INTO PLACE. A KNEE DISLOCATION SHOULD ALWAYS BE SEEN IN THE ER READ MORE
Pills I was given at the clinic?
THIS IS TRAMACETTE. IT IS MADE IN CANADA, IT HAS 2 MEDICATIONS IN IT, BOTH FOR PAIN. ONE IS TRAMADOL, THE OTHER IS TYLENOL. I ASSUME THEY GAVE IT TO YOU FOR THE DISCOMFORT ASSOCIATED WITH THE VAX SHOT. READ MORE
Swallowed bottle cap?
MOST LIKELY. IF YOU SWALLOWED IT AND IT MADE IT TO YOUR STOMACH, IT WILL GO THROUGH YOU GI TRACT FINE. LIKELY WILL POOP IT IN 24-48 HOURS. YOU WOULD BE AMAZED AT WHAT WILL PASS THROUGH. NEEDLES, RAZORS, SHARP OBJECTS. IT IS MAINLY IF THEY GET STUCK IN THE THROAT OR ESOPHAGUS THAT WE WORRY. AS LONG AS YOU DON'T START HAVING ABDOMINAL PAINS, VOMITING ETC, YOU'LL PROBABLY FIND IT IN THE TOILET IF YOU LOOK READ MORE
Which position is the best to stop bleeding from the nose?
HEAD LOOKING STRAIGHT FORWARD. SPRAY AFRIN NASAL SPRAY IN THE NOSTRIL, THEN PINCH THE NOSE FOR 5-10 MINUTES. IF STILL BLEEDING, AND A LOT OF BLOOD, GO TO THE ER READ MORE
I messed up?
A SINGLE DOSE OF THAT SHOULD BE NO PROBLEM. JUST DON'T CONTINUE THAT! READ MORE
Ethical query?
THIS IS A GOOD QUESTION. IN MY OPINION, THE FIRST QUESTION I WOULD WANT ANSWERED IF I WAS THE ATTENDING PHYSICIAN IN THE ED AND THIS PT WAS BROUGHT IN, IS 'SHOW ME THE DNR"! IS IT A TRUE AND LEGAL DNR. UNTIL I HAD VERIFICATION OF THAT. I WOULD TREAT THE PATIENT JUST LIKE ANY OTHER. ONCE I HAD WHAT I FELT TO BE A TRUE AND LEGAL DNR, I WOULD STOP, OR IF IT HADN'T BEN STARTED, I WOULD FOLLOW THE DNR. ESPECIALLY IF I HAD FAMILY, ETC., TO VERIFY. THE ETHICAL AND MORAL ISSUE HERE IS CLEAR. YOU FOLLOW THE PATIENT'S WISHES, BUT FIRST YOU MUST VERIFY THEM. THIS IS A COMMON DILEMMA IN THE ED. READ MORE
Abdominal pain?
I AM A LITTLE CONFUSED, BUT IT SOUNDS LIKE YOU HAVE LEFT-SIDED ABDOMINAL PAIN. FIRST, STOOLS WHICH ARE BLACK CAN BE FROM SEVERAL THINGS - EVEN TOO MUCH VITAMIN C. BUT BLACK STOOLS MAY BE A SIGN OF PEPTIC ULCER DISEASE WITH BLEEDING IN THE STOMACH. THE ACID IN THE STOMACH MIXED WITH BLOOD FORM A BLACK STOOL. I DO NO KNOW WHAT TESTS YOU HAVE HAD. I WOULD EXPECT, BASED ON YOUR SYMPTOMS HERE, A CT SCAN OF YOUR ABDOMEN AND PELVIS AT A MINIMUM. YOU MAY NEED EGD, COLONOSCOPY, A TEST FOR H. PYLORI, AND THEN DEPENDING ON WHAT IS FOUND OTHER TESTING. A DR SHOULD CHECK YOUR STOOL FOR BLOOD, WHICH IS A VERY SIMPLE TEST. BUT IF YOU HAVE SEVERE ABDOMINAL PAIN, DO NOT IGNORE IT, IT IS STILL WORTH A TRIP TO THE EMERGENCY ROOM. I COULD LIST DIAGNOSES CAUSING SEVERE ABD PAIN, BUT IT WOULD BE TOO LONG. READ MORE
What can happen if a fever gets too high?
IN GENERAL, NOTHING DANGEROUS. THERE IS NOT A NUMBER THAT IS NECESSARILY AGREED ON THAT IS TOO HIGH. CLEARLY, IF YOU HAVE A FEVER, YOU SHOULD TAKE TYLENOL AND IBUPROFEN, AT THE SAME TIME - DON'T ALTERNATE - TO BRING FEVER DOWN. IT IS THE PEOPLE WHO ARE OUTDOORS IN HEAT THAT DEVELOP LIFE-THREATENING HEAT ILLNESS THAT ARE IN DANGER. ALSO, OTHER THAN GETTING YOUR FEVER DOWN, YOU SHOULD SEE A DR TO FIND OUT WHY YOU HAVE FEVER. READ MORE
Will the ER remove hemorrhoids?
IT ALL DEPENDS ON WHERE THE HEMORRHOID IS, IF IT IS THROMBOSED, AND THE ER DOCTOR. SOME ER DOCTORS ARE MORE LIKELY TO REMOVE THAN OTHERS. IF THE HEMORRHOID IS PAINFUL AND ON EXAM IT APPEARS TO BE A CLOTTED MASS, THOSE CAN BE OPENED TO LET THE CLOT OUT AND WILL RELIEVE PAIN. SHORT ANSWER IS YES. READ MORE
What are the signs of a diabetic emergency?
FIRST, IN MEDICINE, DIFFERENT PEOPLE SHOW SIGNS IN DIFFERENT WAYS. IN GENERAL THOUGH, THE MAIN DIABETIC EMERGENCY IS DKA-DIABETIC KETOACIDOSIS, A VICIOUS CYCLE OF ELEVATED BLOOD SUGAR, LEADING TO VOMITING AND DEHYDRATION, AND THE FORMATION OF BLOO KETOACIDS. PATIENTS WITH THIS WILL APPEAR VERY ILL, WILL BE VOMITING, LOOK AND FEEL DEHYDRATED. THEY NEED HOSPITALIZATION READ MORE
When should you go to the hospital for heavy bleeding?
DIFFICULT TO ANSWER. I ASSUME YOU MEAN HEAVY VAGINAL BLEEDING. THERE ARE SEVERAL VARIABLES TO CONSIDER. HOW MANY DAYS YOU HAVE HAD THIS; YOUR OB HISTORY; MEDICATIONS YOU TAKE; BUT ESPECIALLY IF YOU ARE HAVING OTHER SYMPTOMS OF ANEMIA FROM BLOOD LOSS, SUCH AS LIGHT HEADED, PALE EYES (THE WHITE PART OF EYE) WEAKNESS. AND IF ABDOMINAL PAIN IS A CHANGE, OR IF YOU HAVE ASSOCIATED FEVER. I RECOMMEND TALKING TO YOUR OB/GYN FIRST, BUT IF YOU HAVE SEVERE SYMPTOMS THEN BEST TO BE SAFE AND GO TO THE ER. READ MORE
What can happen if your blood sugar is too high?
THIS IS A QUESTION THAT IS DIFFICULT TO GIVE A SHORT ANSWER TO. BECAUSE SO MANY VARIABLES INVOLVED. IT DEPENDS ON; EXACTLY HOW HIGH; HOW LONG IT HAS BEEN HIGH; OTHER SYMPTOMS WHICH ARE POSSIBLY NUMEROUS. IF YOUR BLOOD SUGAR GETS HIGH, IN GENERAL THE CLASSIC SYMPTOM ARE CONSTANT THIRST AND CONSTAN URINATION. IF YOUR SUGAR GETS HIGH ENOUGH, YOU CAN END UP IN DKA, THE SEVERE END OF THE SPECTRUM, AND THESE PTS NEED TO BE IN HOSPITAL. THERE ARE ALSO SEVERAL PROBLEMS THAT MAY DEVELOP WITH LON TERM HIGH BLOOD SUGAR. THE LIST IS LONG. GET YOUR SUGAR TESTED, THEN GO FROM THERE. YOU CAN ALWAYS GOOGLE SYMPTOMS OF HYPERGLYCEMIA FOR INF AS WELL READ MORE
Do I need medical treatment after breathing in lead paint?
ONLY IF YOU ARE SYMPTOMATIC. IF THE PAINT WAS RECENT IT SHOULD NOT HAVE LEAD IN IT. IT'S THE OLDER PAINTS THAT HAVE LEAD READ MORE
What should I do if my blood sugar is over 300?
GO SEE EITHER YOUR PCP OR AN EMERGENCY ROOM, OR BETTER YET AN URGENT CARE CLINIC. A SUGAR THAT HIGH NEEDS TREATMENT READ MORE
Can you go to the ER for neck pain?
YOU CAN, ESPECIALLY IF TRAUMA TO THE NECK WAS INVOLVED. IF THERE WAS NO TRAUMA, AND THE PAIN HAS BEEN THERE FOR MORE THAN A WEEK OR 2, BETTER TO SEE AN URGENT CARE OR PCP, AS AN MRI MAY BE NEEDED. READ MORE
What is the first aid treatment for a heart attack?
THE FIRST THING TO DO IS BE SURE THE PATIENT IS BREATHING AND HAS A PULSE. BASIC LIFE SAVING COURSE IS HELPFUL. BUT TAKING A FULL STRENGTH ASPIRIN, UNLESS CONTRAINDICATED, IS FIRST, AND THEN ANY MEDICATIONS YOU MAY TAKE FOR BLOOD PRESSURE TO KEEP BP AT A GOOD RANGE. THEN IF YOU ARE TRULLY HAVING CHEST PAIN, GO TO AN ER OR CALL 911 READ MORE
What are the symptoms of appendicitis?
DEPENDS ON SEVERAL VARIABLES. EXACTLY HOW LONG, ANY OTHER SYMPTOMS SUCH AS FEVER, NAUSEA, DIARRHEA, DECREASED APPETITE, IT IS POSSIBLE IT COULD BE APPENDICITITS. THERE ARE KNOWN CASES OF PATIENTS WHO GET A CHRONIC APPENDICITIS. THEY STILL NEED IT REMOVED. IT COULD ALSO BE OTHER THINGS NOT SURGICAL,E.G. A MECKELS DIVERTICULUM, COLON DISEASE(MULTIPLE TYPES) A HERNIA, AND OTHERS. I SUGGEST YOU SEE A DR AND LET THEM GET THE HISTORY AND EXAMINE YU READ MORE
When an ear infection is serious?
Rarely. There are infections of the ear canal, the eardrum (TM), and the inner ear. Canal infections often called swimmers' ear but not always associated with swimming. Easily treatable. The latest guidelines to treating otitis media - which I assume you are talking about, recommends (at least in pediatrics) for mild cases not to use antibiotics, as these are often viral. still a lot of debate about this. The distinction between mild, moderate, severe is vague in the 2019 guidelines that came out. The complications of an ear infection are rare, especially if treated with proper antibiotics. but they are as follows; 1. perforation (rupture due to inside pressure) of the eardrum, the tympanic membrane. 2. if a patient is immunocompromised, a serious complication could be sepsis, septic shock. Again, rare for an ear infection to cause this. 3. they can travel to the sinuses, the mastoids, and sometimes even the brain, and cause meningitis. I can't say enough that complications like these are very rare. Most ear infections will resolve on their own or with antibiotics. READ MORE
