i had a bad fall about 4 yrs ago, hit the back of my thigh and had a major burise. xray showed nothing. bothers me every now and then. seems to get worse when the weather changes. i have tenderness in the exact spot of the burise and i seem to have an ache from there all the way down my leg. no sewlling or redness not even hot to the touch. WHAT is going on?? any one have an idea!!
