Uncomfortable pain under my armpit—anyone dealt with this?

Over the course of the last few days, I’ve been contending with this rather unsettling stinging sensation right under my right armpit, accompanied by a dull, nagging ache that seems to radiate down my arm and across the right side of my back—almost as if I’ve somehow overextended a muscle during some strenuous activity. I haven't felt any lumps or noticed anything out of the ordinary upon inspection; there is simply this persistent discomfort lingering there. Has anyone else here navigated a similar situation?

It actually happened. No clue how, either. Just went down out of nowhere.🤷

Maybe you did, or maybe you just pinched a nerve somewhere, because I know how it goes when I'm driving and I suddenly stretch the wrong way and everything just flares up...

Apply an alcohol compress and go see a surgeon...

Things are feeling significantly better today, if I do say so myself; I’ve been applying pressure, though it isn't the actual pressure that causes discomfort—it is more of a persistent stinging sensation on the skin itself. I suspect it might be a reaction to shaving or perhaps the application of spray deodorant, as I recall reading somewhere that those products can clog your pores and trigger these kinds of inflammatory issues... Has anyone else here dealt with something similar? I find myself wondering if a consultation with a surgeon is absolutely necessary, and truth be told, the thought of it makes me a bit anxious. 😕

Forget the surgeon... 😕

Here’s my take on the situation 😢
My skin isn't burning—no swelling, no lumps or anything weird like that—but there’s definitely pain. Or maybe "discomfort" is a better word for it. It doesn't really bother me when my arm is resting against my side, but the second I try to fully extend it 😕, it hits me. Should I go see a doctor? Or maybe just slap some ointment on it and hope for the best?
