There will be swelling over an area of muscle, often with a reduction in pain of the compartment that has been under pressure.
Signs and alternative diagnoses
Your doctor will see and feel the same enlargement that you do, and will want to rule out infections, tumours, foreign bodies and other causes of unexpected bumps.
These will only be used to eliminate the alternative causes.
You probably need to do very little, unless RICE is needed to ease local discomfort.
Unless you wish to pay a large sum of money, the doctor will be unwilling to treat a defect which is purely cosmetic, and risk causing a compartment syndrome.
Can you run through it?/Recovery time
It is unlikely that youll need to have much time off, if any, and the permanent swelling will probably become just another object of mirth at the club!
