What Could Cause A Tingling Sensation Around The Anus And Pain In The Tail Bone?

So on Friday night I felt a tingling on my bottom around my anus. At first I thought it was pin worms because I work at a vet and one of my coworkers had had them a few days befor. So I got Reese pin worm meds. But I didn’t notice any in my poop or any other signs of them. It still felt the felling sat and Sunday night. Now Monday there is a slight burning sensation there. I checked and there’s no sign of rash or anything visible. I also have some pain on my tail bone don’t know if it’s related or not but just thought I cover everything in case it’s related.
