Hi,I Now At This Time Have Some Underlying Symptoms Of

Hi,I now at this time have some underlying symptoms of something that no body can tell me whats wrong.But right now my question is......I thought that somewhere at one time i heard that a symptom to some sort of nerve problem is as follows,any and all places on my body that my clothes tend to cause any marks,the marks tend to itch NON-STOP,i mean i can just about draw blood with no relief.my symptoms i have had for several years now are;from more bothersome to less bothersome:#1 from time to time my left leg from the knee down will swell up to double its size,however my right leg at the same time doubles the amount of the left leg,i have great knee pain in my right leg,i cannot bend it without tremendous pain,plus it hurts constantly anyways,both legs but again more so in the right one,when swollen becomes as hard as a cast and is very heavy like a cast,i have to assist in lifting of that leg when getting in and out of any vehicle.not easy getting dressed either,most of my jeans wont fit because of the calf being so large i cant pull them up all the way.# 2 my toes and various parts of my feet are numb,yet very painful from spasm stinging feelings,or sudden shots of pain at times.# 3 the upper quadrant of my back on the left side has 70-99% no feeling,yet there is one spot that constantly itches,but i cant feel myself scratch it,it feels like i have ten sweaters on,so i am careful not to dig a hole there when its at its worse I don't know if these symptoms are related to the leg problem.# 4 i have severe restless leg feelings predominately in my right leg,its like i need to stretch every muscle,but yet i have to keep from moving anything around my right knee,or i am in bad pain.
