Hello...my husband has been experiencing chronic dizziness, weight loss, sinus pressure, ringing in the ears, and severe insomnia for the last 4 months. He has seen ENTs, Neurologists, Chiropractors, Acupuncturists, had MRIs, CTs, blood panels, and gone to PT but no one is able to diagnose him. He is disabled by this and doesn t really know what else to do. All the doctor s tell him there is nothing wrong with him and that he just has anxiety but that is not the case. He is physically in a lot of pain and is suffering tremendously. His sister has 3 autoimmune diseases and has several of the same symptoms but his blood work is not showing any signs of autoimmune. Any ideas what could be causing this? It came on suddenly back in January.
