Hi, I'm wondering if I could get any advice. I had swollen lymph nodes, behind my ear, neck and groin over a year ago, I had a biopsy done and all was clear. They said they where reactive. So a year on and the lymph node behind my ear is still there only bigger and start to cause sore heads, I went to the doctor and again he said all the tests where done and he doesn't know what's causing it, The lymph node at the back of neck under the skin has now also returned causing pain. Last night I started to get a sore arm and I have just found another swollen lymph node between my collar bone and shoulder. Has anybody any advice.
