Hi, I'm 18 and recently whilst participating in parkour i landed on my back slightly more to the right and since the day after mt back right ribs have been hurting especially when I lift my right arm above my shoulder height it's not that sore to take in a deep breathe in but it is slightly sore when i cough I don't go to my doctors because I suffer from a slight social phobia I was just wondering if there is anything wrong because I've got parkour this thursday coming up
