icollup,
Welcome to the forum. I have many of your symptoms and others that come and go. Each presents a challage in coping skills and trying not to panic. The dizziness is the worse thing for me lately as I am trying to work in my garden. Last summer and fall, I was trying to get small areas of garden ready to plant and bent over too much and so tried working on my hand and knees. When I stood up I was fine for a few minutes then the dizziness hit like a ton of bricks. I ended up in the emergency room. Now I have pills for the dizziness.
So I know what your going through. I have reynauds and some parathesia, and get chest inflamation a lot. Just another gal with fibro. lol
Anyways please join in and post questions and give answers to other's who are looking for answers too. Stop into the pub & tea time and relax and post there as well. See you around the forum.
