It just started, I don't remember hurting the area at all.
Hello Ahatcher,
Welcome to the Pain Management Forum. I am glad that you found us.
I assume that your pain is short term, or new. How long has this been going on? It very well could be a bruise that you just don't recall happening. However it could be an inflammtion in that area also.
Best to consult your PCP. If you'd like to add additional information it may help us, help you with additional suggestions.
Take Care,
