Thank you everyone. You all gave good answers, but I had to pick just one. To Jumong, I think you are right about my tissues not getting enough oxygen. I am going to have to get another doctor who specializes in vascular problems. My upper arms hurt when I comb my hair. I think this if v=from vascular problems, also. And last night I had a dream where a doctor told me that I had blockage in my arteries in my legs. This was scary. Maybe this is what is wrong with me. I have to find a doctor who will listen to me,. and believe me. My current PCP ignored my leg symptoms and did not refer me to a vascular specialist. I don't know what to do? Does anyone know a specialist in Cleveland, Ohio?
I might add that you require a thorough physical. You may have more than one medical problem. Swelling may be due to cardiac issues or kidney problems, among other things. If you have trouble understanding what the doctor says think about writing a medical release and having an articulate member of the family visit doctor with you. Another plan would be to request written copies of all previous exams (there may be a small cost) and have them available to discuss with a trusted family member. 1000 mg a day of crystaline (in a powder form) vitamin C will have many benefits, as well as being a mild diuretic, keeping the swelling down.
Oh - and if your doctor says "you ask too many questions", find a new primary care physician.
It is possible. The tissues in your legs are not getting enough oxygen, and that is very very bad for them.
