So this is a problem I've been having for the past few days - it came out of the blue basically. So in a spot around 1cm up from the base of the penis and then 1cm to the left ([NSFW: highlighted it on a photo I found online](https://i.imgur.com/3Stecpy.png)) I have a painful spot which sometimes causes light pain/discomfort/slight itching inside when walking or standing (veery rarely when I'm sitting down you feel even slighter discomfort). It's very slight but you definitely feel it's not comfortable. The area is not swollen, it's not red, not anything of that kind, you can't feel anything extraordinary there - however, I can pinpoint a spot that's painful perfectly with my finger but even then I need to press it pretty firmly at a specific angle or it won't be painful. I've tried doing various motions with my leg/body to trigger it (jumping jacks, jumping, running, bendind and twisting it in weird directions or across my body, doing squats, what have you) but to no avail. Hell, after it started I even went for a run thrice and had no problems with it. And yet, sometimes getting in and out of a car a few times and walking for a few minutes is enough to trigger it.
It basically feels like I hit myself with something in that spot (which is not the case), it's the same kind of dull "inside" pain. I'm an avid runner, and have been for years, so first I suspected that but I'm not sure as I'm during my offseason now, doing pretty light and short runs (~4,5h/week, certainly had "better" periods for any stress injuries, like preparing for a marathon for example). A new habit I took up on in the past weeks is guitar (started in January but my practice is now longer and more consistent) which I now spend basically an hour a day/every other day on, in a position I don't (and have never) sit in otherwise (my legs noticeably to the left, my upper body straight so that the guitar doesn't slide around, like [this](https://pickupmusic.com/wp-content/uploads/2019/09/posture.jpg) but even more twisted) so I thought about this causing new tensions to my body, too. Other than that, nothing has been out of the ordinary during the past days or weeks. I did not strain myself, did not carry anything heavy, did not do anything new.
What could that be? Because of the covid situation, the queues to the doc's are enormous around here + I'd rather not stand in that line of flu-symptom people for a few hours if I don't need to so I'd rather first try and see if I can simply fix it myself, with resting for example. So far, I just decided to stop running (so I haven't run for the past 3 days and am not planning to till the end of the week). What else should I try? What may the problem even be? Muscle strain, pinched nerve?
