question: Hello I am 31 5'9 and 152lbs I have been going to my doctor for year now trying to figure out why i am having burning feeling in my thighs and calves. Then I ended up with a painful swollen lymph nodes under my arm and a few in my neck. I had one in my neck removed just to find out it was just a dead diseased. I am not really getting any answers. Now the one under my arm is getting bigger and I have two new ones one next to both ankles they are painful and itchy. The only things that have been figured out is that my sodium is low as well as my vitamin D. I am now taking 50,000 iu once a wk. Please any info that could put me in the right direction to finding out whats going on would be wonderful. I feel like I am going crazy..
