Hello everyone. So a few months ago I started getting a dull, achey pain that lasts for a few seconds near the left side of my tail bone. The pain seems to happen a few times a week, and then it will go away for a while, and then come back again. I started getting the pain again this week after not feeling it for a couple of weeks. It will happen randomly a few times a day. I think it mostly happens when I am sitting down, but the last time I got it I was bending over. I know this is a very vague description, but does anyone know what this could possibly be? Could it be a nerve problem, like sciatica even though the pain doesn't radiate down my leg? Or could it be a problem with my colon maybe?
