If you type this sentence, you are now experiencing a pain in the butt. As my second time experience this, I'm tough enough to come in here to share my thoughts of what happen and why it's there to cause such a pain. I notice that your body change over time, I'm 35 and need regular exercise. Bending, sitting and especially games on phones aren't help when you sit on the toilet bowl or more than 30 mins! My problem was I discover I was sitting down to clean my wheels (4) due to rusted brake dust. I spent too much time for each wheel and I endup with this pain in the ass. But last time I had it, it took about 10 days before it will go away, I have tried Preparation H (useless) so there is no medicine will take care of this because your tissue has erupted! Just like a volcano erupt, just let it be. You will feel the pain even more when you laying down. Best suggestion is exsercise regularly.
