I am really trying to find a solid answer on if will go away in 3 to 5 years. This has really been tough. I have only had the hives once. My issue is horrible stomach issues, burning ears, headaches, and the occasional feeling of a panic attack. Three weeks now with no meats and I feel better, but I still have a little nausea everyday with a small headache. For 34 years I thought I was invincible but, this alpha gal will humble you quickly. I guess we all need that sometimes, but I hope this will goes away. Doc said he will check every 6 months to see if its gone.
