Iam currently on a surf trip trough Europe and Africa and I have been surfing for about 1 1/2 months about every second day for a couple hours. Right now I am in Morocco and I surfed without a wetsuit for the first time , 2 days in a row. I took one day off surfing . This morning I could feel an intense pain under my right part of the chest, like 15 cm under my nipple were the rib cage ends. (Sorry for my fleshin' vocabulary

I can't surf cuz just laying on my board is so painful . Does anyone of you know what that is/ had common experiences?
Iam really curious what it is or how long it will last, cause my surf - time here is limited
