I ve been having severe headache on Leftside of my head and ear, then suddenly I observed a swollen at the back of my left ear and neck. I visited doctor I was checked but was told that there was nothing wrong with me. Then three months later I started noticing dandruff in my hair, it became too much that I had to cut my hair to be able to treat well. But it's still there, both headache and the swollen lymph at the back of my ear. In fact my whole left side of my body has been in pain all the the while. Please do you ve any suggestions or answers to this issue. Thanks.
