My only bad experience on C was the 3 times I mustve hit a vein. Wow was it hard to get air in/out of my lungs. The night before I did deep breathing exercises for who knows why. Thank god. I had to lay still as possible, not move, not worry, just get air in and out slowly but surely. My stomach was also in spasm, heart slowed to a crawl but went THUMP..THUMP when it beat. That I dont miss. I still take a shot time to time (maybe 2 per month) when Tysabri isnt cutting it. Hey Dej..I didnt have internet access when I was in hospital! Hope you get out soon.
