Hi, a few days ago I had the dreaded LP. It wasn't as bad as I thought it would be but I was wondering if any one of you had an awful reaction to it? I was fine afterwards and the next day (apart from a sore back) but now I can't seem to sit. I get a terrible stiff neck and sore head. It was so painful that while I was driving to work today I had to pull over to vomit. Not my finest hour! I phoned the doctor whose given me painkillers but just wondering if any one else had this problem and how long before it got better. I can't sit, only lay down or stand.
