I live near the sea and recently swan and when I got out of the sea was covered in a red bumpy rash and felt a little shaky. After about 30 minutes the rash dissappeared and I felt better. Thought I might have been bitten by something whilst swimming as bottom of my back felt tender and there was a small red mark. Then few days later swam again, same thing happened, and then again the next 2 times. It also happened once at home when I took a shower !!! and also once when working hard in garden, working up a sweat. What on earth could it be. I wouldn't be too worried if the rash, shaking wasn't getting worse each time I swam - the last time I spent a long time in the sea as I was windsurfing. Bit worried really as live on an island and spend ALOT of time at the beach.
Thanks for any help you can offer.
