Have had area at side of one knee that started as itchy years ago but not someithing to itch to raw,etc. It has felt at times numb at that area. Recently, I had to apply in that area doing an exercise with a cylintrical (sp) type rubber excercise band. Not too long after I started to feel some itching and something that felt like little tiny electrodes that were moving up my leg. There was more that one area this happened in on the upper leg and the feelings were sparatic sp) Basically, as tho there were little creepy crawlers in there with there fronts having or making the sensation of tiny electrodes. The seemed to have moved from the original area upward. The electrodes would go on and then it'd stop, then go on and stop and as tho it was moving. Would this be an infestation of some kind of mite, parasite? No outward signs that I can tell much. think something dormant may have been activated.
