On December 13, 2016 (Last week) I dove in Barbados and rubbed my leg against a moor 40 feet down that the dive boat was tied too. A big cement moor. Immediately my leg started burning. The burn lasted for a day then went away. There was never any red rash or swelling during the burn. In fact, you could not see anything unusual on the skin, just the pain. Its now a week later and that same area of skin is now a red itchy rash. Has anyone else experienced this and anyone know what this might be? Yes, I know I need a doctor and I will go, but curious if anyone else ever had this. Ive been diving for many years and never experienced this before.
