After brain aneurysm and removal of the aneurysm, there were symptoms of irregular gait, numbness on the affected side, and for the last two years gradual clear fluid from nose and atrophy of the nose. A biopsy determined there was no cancer, however the skin turns red, then grey then bleeds and the skin begins to dissolve. There have been tests to determine if spinal fluid is causing the atrophy, however, the only doctor who had a vague explanation said t could be the trigeminal nerve. There is sporadic pain, but there has been no explanation about the atrophy. Do you have any suggestions as to what specialist to consult.
