This is embarrassing but here goes. Did 4 dives last Saturday. First dive I had a problem and went into deco, dive was to 108ft, did a deep stop at 60 and deco obligation of 4 mins at 15ft on 40%., both computers cleared me 1:15 si. 2nd dive to 84ft, bt 12 mins, safety stop 5mins at 15. 1hr si. 3rd dive to 43 mins for 22mins with 5 mins safety stop. 20 min si. 4th dive was 27 ft for 20 mins w/ 5 mins ss. That was quite a bit of diving however with the exception of the 1st dive my nitrogen levels were well within acceptable range. Other than the 40% on deco, it was all air diving. The pain started the next day in my shoulders but I figured it was just from clipping s/m steel 100s on and off. There is no joint pain and just more of an irritation than pain. I am now having some aches in my upper left arm and both legs below the knee, it is not constant. I do have back problems which could be causing this but I am just wondering if I am overreacting. Seems like the pain would be unbearable 4 days later. Btw I am a member of DAN and a tec 45 diver. Maybe I should give dan a call. Opinions?
