In reply to Paddy98:
I know I speak for most people on UKC when i recommend some exploratory self-surgery. You'll need soap, hot towels, a carefully positioned couple of mirrors and a Stanley knife (sterilised). Ice cubes help to numb the areas of interest...
Plan B: Go to your doctor and get a referral to a sport specialist. Seriously, this could be a range of issues and you need to get it sorted - earlier the better.
It think it is safer to solicit advice on UKC on the back of a formal diagnosis rather than symptoms.
