Blister above my belly button

Hey. I've had this weird little Bubbles under my skin for about three years now—located right about three fingers above my belly button. It doesn't really bother me most of the time, but when I'm hitting the gym, I can feel it tightening up, though there's no actual pain. If I press on the Bubbles, it shrinks down and it feels like the fluid or whatever is inside just shifts somewhere else (it doesn't fully disappear, though, so I'm a bit scared to squeeze it too hard). Could this be a hernia or maybe just some kind of cyst? Thanks in advance

Based on that description, it sounds like it could be a hernia or a bulge, but you really can't know anything for certain without a professional exam. You should go ahead and 🙂

It’s super likely that’s what we’re talking about, bruh—that little guy right near your belly button. Honestly, those tiny ones can be way more sketchy than the bigger ones you get in the groin area. You should probably hit up a doctor ASAP; they’ll most likely just tell you that surgery is the move, and sooner rather than later...
Hang in there! 👍

So, you're saying it wouldn't be a smart move to keep hitting the gym until I get this sorted out? :-/

Look, before you push yourself too hard, you really need to have a doctor—ideally a surgeon—take a look at it. They need to assess the actual size of the hernia and the risk of it becoming incarcerated or strangulated. In the meantime, I’d suggest dialing back the intensity at the gym.
I wouldn't lose too much sleep over the risk of strangulation if you've been training at the gym for three years now without any issues.

Generally speaking, those epigastric hernias located above the navel are the least dangerous and are rarely a candidate for surgery, unlike inguinal or femoral hernias. Of course, everything depends on the specific size and placement.
If it does turn out that you need an operation, don't worry too much; it isn't anything to fear. 🙂
