My son (16) plays a lot of racket sports. He's not at a particularly high level but he does play several hours a week. He gets the odd pulled muscle and (not being remotely sporty myself) I don't know whether this is something to worry about? At the moment I stick a bit of deep heat on it and give him some ibuprofen and if it doesn't go after a few days then I would take him to minor injuries. But should I be taking him to a sports physio or similar? I'd like him to look after himself as he becomes an adult but I don't really know what an appropriate level of intervention is.
