Hay Luschwitz,
As much as I love to give pseudodiagnosis for injuries, without a LOT more information I can not accurately even begin to diagnose your injurySorry. It will likely be more time efficient to get this checked out by your local therapist. Keep us in the loop with what he diagnoses and we may be able to help give advice on treatment plans / exercises / return to sport
If you are stuck in the middle of no where and simply can not get to a physical therapist, let us know and I will try and give you a list of questions to answer to help reach some form of diagnosis or advice.
Thanks, musculoman!
