Every since my appendix surgery I haven't been the same. I can't walk or run a long distance without my legs hurting. I feel like if I over do it during the day is when I have my leg attacks at night in my sleep. I have never felt a pain like this in my life. It's just in my thighs! When I have these attacks and wake up my legs are soaked and I can do nothing but scream. After my attacks my legs are worthless for days. Can someone please tell me what the heck is going on?!!
