pulled a muscle or something,?

Hello and thank you for posting your medical question on E health forum.

The history and the symptoms described here seem to indicate that you have musculo-skeletal pain. This pain is reproducible on application of pressure at the place and when a activity that brings it on is repeated. Adequate rest will relieve the pain.

The pain of appendicitis is constant and does not change with posture as describes by you. It is also associated with other symptoms like high fever, nausea, vomiting, etc. The pain is not relieved by rest.

You may try some OTC pain medications to relieve your pain.

You may consider to consult your doctor if the symptoms seem to be worsening or not improving. He can evaluate your condition and diagnose any other conditions if present.

I hope this helps.
