Dear Realowl,
What you have described could certainly be epididymitis. This condition should be treated once it is diagnosed, because the longer it goes without treatment the more difficult it would be to treat. You don't necessarily need a urologist to treat this condition. Your primary doctor or the doctors at the walk in clinic should know what to do. The usual treatment includes antibiotics for two weeks, in addition to anti inflammatory medications to help relieve the pain and swelling.
As far as follow up, it would be wise to see a urologist for a definitive evaluation. As a rule a urologist sees a testicular mass right away, unless the process is more suggestive of an infection/epididymitis. If you are started on a course of treatment with antibiotics before your scheduled appointment, the ten day wait would not be a problem in case of epididymitis.
If you are evaluated by a primary doctor/ walk in clinic, and they find a mass on your testicle which is concerning, then they should be able to get you an appointment with a urologist right away. Regardless, you must be seen by some one soon.
