I've been dealing with some mild pain in my lower abdomen on both sides for the past few weeks, and I'm getting a bit worried. Plus, there's this extra skin forming on the tip of my anus over the last couple of months, and it's slowly getting bigger. On top of that, I've noticed some muscle lumps in other parts of my body for about two years now, although they haven't grown. I'm concerned about what might be going on and would love to get your thoughts.
