Our newest diver in the group suffered from tingling legs and left arm after a day of diving and DAN was quick with a response to answer all questions. Might have been a slight case of DCS, but symptoms resolved without treatment.
After the morning dives, one deep and the second shallow, he went out snorkeling and did some 30-40 foot free dives to get some Conch. In the early evening, he started to feel like his legs were going to sleep and then his arm. By morning all was good. DAN had the answers, and recommended medical treatment if symptoms got worse but not to panic about it. I think just talking to the Doctor had a tremendous calming effect. I believe he is now a DAN member, don't leave home without it.
He was done diving for the vacation, but already has plans for another dive vacation, albeit without the afternoon swims.
Other than that, Cayman Brac came through with more spectacular diving. Never a bad dive.
