My son had become ill last spring. His symptoms included headache, dizziness, numbness in legs, after many test the DR. concluded it was migrains and put him on pain killers, which did not work. Then as the winter started to aproach his symptoms began to go away. He was fine for several months finally feeling his old self again. Then came the spring of this year and he began to get sick again, this time he has vision problems and hearing loss, pains in his legs and is very dizzy. Again back to the DR. and the clinical diagnosis was MS, but after all his test came back negative the DR told us he couldn't help and sent us on our way. Please advise as to what we should do next. My son is sick and getting sicker
