Dear Ada, Please don't ever be afraid to ask a question. The fact that some of us are more severely impacted by this condition does not in any way diminish what you are going through. As for the cooler water please be careful. I tried a public pool with cooler water and I was miserable for the rest of the day. So, if you are going to try it ,may I suggest just going in for a few minutes the first time. If you do O.K. then perhaps you could gradually increase your time. Hope this helps.....Jeannie
