What tests are needed for kidney stones?
If the pain is tolerable, go to your primary care physician who will probably order an ultrasound. If the pain is intolerable, meaning it wakes you up from sleep or prevents you from going to sleep, go to the ER. The ER doc will most likely order a CT scan without intravenous contrast if he thinks the pain is due to stones.
Make sure your husband drink a lot of water all the time unless he has a heart condition of some sort or kidney problems because the water will help prevent formation of stones.
Take care.

How many radiation therapy sessions would I require for metastatic cancer?
The number of sessions depends on:
1. What is the primary cancer such as breast, lung, colon...
2. Whether you have been treated before in the area of metastasis and it is coming back (every tissue has a limit as far as how much radiation it can tolerate without creating problems for you; you can only get a smaller amount of radiation if you were previously radiated in the same area.
3. How big the metastasis is and what the radiation oncologist has to do (be creative about irradiating a large amount of tissue without damaging surrounding tissue too much).
4. What method is used to treat the metastatic cancer (small doses given 3-5 days a week over 3-6 weeks vs large dose to a small amount of brain tissue in 1-2 doses).
You can ask all those questions to the Radiation Oncologist (doctor who treats your metastatic cancer with radiation). I am a diagnostic Neuroradiologist who reads your MRIs, CTs of the brain, spine and neck, of cancer patients, but does not treat the metastatic disease that I diagnose.
Take care.
Can radiation therapy work for arthritis?
I have not heard about radiation therapy used for arthritis, although I must say I am a diagnostic radiologist who reads CTs, MRIs, plain films, etc. I do not do radiation therapy, which is practiced by radiation oncologists.
From a holistic medicine standpoint, I did not use pain pills when I broke and dislocated my foot (Lisfranc fracture requiring surgery, cast, 3 months in bed, 3.5 months of physical therapy). I ate 1 tablespoon of extra virgin organic coconut oil with food every 8 hours, which worked like a charm to decrease the pain so I can do physical therapy exercises. The brand is "Garden of Life" and you can buy it online at Vitaminshoppe.com. It comes in a glass jar. Do not buy coconut oil that comes in plastic jar, because plastic leaches toxins out, especially when in contact with oil. Coconut oil is a wonderful substance. Bruce Fife ND has a book on Amazon.com about coconut oil and arthritis: "The New Arthritis Cure: Eliminate Arthritis and Fibromyalgia Permanently, 2012 Kindle edition. Buy it and read it. Being on a vegan organic diet will also reduce inflammation. If you don't believe in all this, forgive my info and advice. I am just sharing what I do for myself, not what traditional textbook medicine teaches.
Is a CT Scan safe during pregnancy?
The amount of radiation can be decreased by having the patient's abdomen and pelvis wrapped in lead aprons during the CT scan. The amount of radiation is different on different CT scans (less in newer CT scans and more in older CT scans). The amount of radiation is less harmful to a 4-month-old fetus than to a 1- or 2-month-old fetus. Everything is relative and the health of the mother is a big issue here, if the mother is having significant headaches. Please discuss further risks and benefits with your physician or local radiologist where you will have the CT.
My X-ray showed a 3mm stone in the right kidney however it was not seen in the following x-ray. Why did this happen?
Scenario 1: You probably passed the stone during the week, which elapsed between the 2 X-rays, which would be good news, specially if you are no longer in pain.
Scenario 2: If you are still in pain, you may still have the kidney stone, although there might be other shadows obscuring the right kidney on X-ray that prevent the radiologist from seeing the stone on X-ray. If you are still in pain, you might need a CT of the abdomen and pelvis without intravenous contrast (the ultimate test) to determine whether you have a stone in your right kidney or not. This is the best test to check whether you have a stone or not.
