I am a member of the roller derby. About 2 weeks ago I fell on my knee and impacted the lateral aspect of my knee just below the patella. I have considerable swelling a pain, bruising down my shin and just below my ankle. I don't have insurance right now and I have only had access to a GP who diagnosed bursitis, put me on Naproxen 500mg b.i.d. and told me to keep a compression wrap on my knee. The lump has gone down some but is still hard and tender to the touch. I am very concerned that there may be more to this scenario than just bursitis. Could you give me suggestions on what some alternative diagnoses might be? Should I go through the ER in order to access an Orthopedic physician?
