Can I just list all the things that worry me. Chronic back pain , all of back, severe in lumbar causing spasms. Lower leg pain, cramping, stiffness . Insomnia and excessive sleeping during the day, migraines (head and ocular), recurring long lasting eye twitching, irrational fear, anxiety resulting in rapid breathing, crying chills sweating. Heat intolerence. Chronic stomach pain, constipation, stomach acid& vomit in throat and mouth. The worry of thinking something might be seriously wrong scares me which makes my anxiety worse which worries me even more.
