Help 😫

So starting yesterday I began getting like a sharp pain feeling in the area circled in blue.

It was so bad I had to leave a post-graduation event because i just couldn’t have the fun I wanted. (It wasn’t like severe pain it was just I couldn’t do the serious physical activity that would be included) every now and then it calms down to where I don’t really notice it before it flares up again and since a few hours ago it hurts more in the area circled in Red. does any one have any idea what might be causing it
