Suggest Remedy For Extreme Pain With Heat Sensitivity In The Thighs

I am 39 5 2 and weigh more than I should, I have EXTREME pain in the front of my thighs. I have knotts, heat sensitivity, tingling, not to mention I lose my balance and fall. I remember the first time I felt this pain when I was 15 running bleachers for soccer. I would have a cycle where the pain was always there, especially walking fast, on incline, or stairs, but I was able to manage it . For about 3 months it was fine and then there would be a month or two that it was difficult to deal with, then it would go back to what I considered normal Now I have days where I cannot get out of bed nor tackle the stairs. I had a breakout of shingles 2 years ago and since then my legs have gotten extremely bad. I have been to many doctors, and a few thought I need to see a psychologist. It s offensive because I went from being active to being on pills, gain weight and can t walk long before the pain is to much. Do you have any ideas because I am sick of being sick . I want me back!
