I've been having a pins and needles feeling in my right hand, the thumb, index and middle finger. Sometimes in my lower arm below the elbow. I was diagnosed with bursitis in my right shoulder and tennis elbow about four weeks ago. I was put on a seven day dosage of steroids. It was after I finished the steroid treatment that the pins and needles feeling started. It doesn't prevent me from using my right hand, but it's just very bothersome and happens out of the blue.
