You are young and that is on your side. I am sorry about your mother. I am sure you are under stress and suffering from the loss. Your symptoms are not distinct. They are typical of anxiety. But we need to rule out a systemic disorder. I am glad you had the Covid test and it was negative. Here you get my strict orders: Wear a mask ALWAYS when away from home. If someone comes to your home, wear a mask. 20 seconds with good soap of vigorous hand washing. Social distancing at least of 6 feet, more is better. Hand sanitizer on you and use it! I carry a small spray bottle of medical alcohol in my bag and I spray the handles of shopping carts even if they “have cleaned” them. Okay, back to your symptoms: you need to see your primary care physician. You are too old for a pediatrician. You need a Family Medicine doctor. So, schedule an appt with a primary care doctor and be sure you go to the appointment. You say you are hot and have heat. Have you taken your temperature? If not, buy a good thermometer you keep in a location you’ll remember. I say this because I'm bad about misplacing mine! You need some blood work drawn. You need a Complete Chemistry Panel, a CBC, a thyroid screen including at TSH with a free T3 and a free T4. And an HgbA1c. It tests your blood sugar over a 90 day period. And any other testing your doctor orders. Print out this email so he/she can see what I have discussed with you. You told me your mother is deceased from the Corona virus. I figure besides grief, you have developed some degree of increased fear of covid. Follow self protection measures and take good care of your body. Eat well, begin an exercise program your primary care doctor agrees to. And get plenty of sleep. Go to bed at a decent hour. I also recommend you find a counselor/psychologist so you can have a professional you can speak and work with. And think about this...the majority of Covid cases do not die. We hear about the ones that do and you lost your mother this way. Chronic medical problems and age above 65 increase mortality. You are 20 years old. If you follow protective measures, which I think I have stressed well, and take care if you do get it and have early medical attention, from your PCP (primary care provider...DO, MD, NP, PA) your chances are good. I hope this has been helpful. Now go make that appointment with a PCP and find a counselor.
Blessings,
Anna Duncan, DO
