Lately I've experiencing something like needles pricking me all over,itching and shortness of breath and I wonder what could be causing this,also in an unrelated matter my right knee's been hurting for nearly 3 months now,and I wonder what could be causing this,thanks and please answer me as soon as possible.

You need to see a doctor about your symptoms. The needles thing can be some sort of neurologic disorder. You could have a pinched nerve somewhere causing this symptom. As far as your knee is concerned, have you injured your knee or did it start just hurting all by itself one day? You could possibly have the beginnings of arthritis in your knee. The shortness of breath has me very worried about you. For that reason alone I would see a doctor. You may have the beginnings of asthma.

Sounds more like a alergic reaction but in all cases esp with breathing issues, a doctor visit is a must

My ex mother-in-law complained about similar symptoms (except for the breathing problem). She said it was fibromyalgia or something like that. I don't think it's a recognized disorder in the medical community as yet though. But definitely don't take my word for it, I'm nowhere near being a doctor.

Fibromyalgia is, in fact, recognized by the medical community.

Do you get your medical info the same place you get your legal info?
