About an 1.5 hours after our 2nd dive on July 13th my foot went numb and tingly while reviewing pictures in the room, eating lunch and getting ready for our next dive. Then Susie noticed what we later learned was skin bends covering most of the lower half of my back. (Redness with purple bruising throughout) We hadn't violated our dive tables, but we also hadn't taken any days off in our 13 consecutive days of diving. At the hospital my symptoms started to dissipate after being on oxygen then went away completely after my champer treatment. I was pretty tired when I exited the chamber, which is evident from the pictures.
