A week ago i started noticing some itching sensation on the right half of my body, especially my lower arm, thigh,buttock and lower leg. Recently this sensation became a bit more intensified and i could feel it gradually crawling up to my face. Currently I feel this itchy sensation primarily on the right side of my face and the soles of my feet(Mostly my right sole and occasionally my left).
I have had a history of knee pain which i have always felt was trivial. However the itching sensation in question started from my right knee long ago, and would come and go intermittently along with the pain. What is happening to me??!! please help me i am so scared
