Mystery bumps all over penis - can’t identify?

Hoping someone can diagnose this for me. About 4 days ago, i noticed the appearance of a number of large red bumps on the shaft of my penis. First instinct was mosquito bites but there were too many and probably too large. Then obviously jumped to Herpes... But they don't look like any herpes sores i can find online. Perhaps scabies? Again cant find too many pictures of these on the penis online to compare against. Or maybe just not a typical herpes? They've seemingly not got any better or worse over the last few days, but have changed appearance from being bumps to circular mini volcano craters (best way i can describe) - some with a red, scab-like 'crater'- others without. Some smaller not quite perfect circles and with white dry skin present. Not itchy, and not particularly painful (i think its more mental anguish) - perhaps a little uncomfortable at times when wearing tight underwear - and no puss/discharge. At times, some have glistened slightly but don't seem to be oozing anything gross. They've also never formed blisters like herpes seems to do from the majority of the pictures I've seen- they've just been fleshy bumps and then directly to these 'crater' like things - not sure if they are really ulcers or not. Went to my GP today, who also isn't sure if its Herpes or not, so he referred me to a urologist who i will only see in a week unfortunately! I asked for a full screen STI blood test which i will have the results back from on Monday - so another 4 days of anxiety, and 7 days before the specialist can examine. So, not ideal - and not sure what to do in the interrim. I've attached pictures of how its progressed over the past 4 days, from relatively benign looking to more pronounced and worrying-looking. Hopefully some ideas from the forum?!

Any suggestions for self medication until the specialist appointment perhaps?

looks like herpes mate.
should be either herpes or syphilis.
but if it comes and goes (bumps become ulcers and vice versa) it’s much likely herpes.

in terms of self medication. just don’t touch it. just let it be.
for mental anguish try lean meat instead of red meat.
and stuff with anti oxidants. like blueberries, grapes and all that.
also have one vitamin c pill a day.

a doc once told me herpes is more of a “cosmetic” thing now. So don’t worry if it is herpes either.
just don’t touch it and touch other places of ur body cuz it can spread cuz it’s an open sore.

best, take care champ

Thank you - seems like its the most likely.. Appreciate the advice - will do my best!
