I have experienced ringing in ears, headaches, electro-sensitivity, neck pain and itching/crawling sensations (predominantly from the shoulders up) for the last year. All this is making me crazy. Finding a doctor who is sympathetic, knowledgeable and doesn't prescribe as if it was psychological is challenging. I have a titanium shoulder implant. Initial testing indicates a sensitivity to titanium alloys. I'm reaching out here to find others with similar experiences and possible remedies.
