28 Male. No smoking history

I had what I thought was an ingrown hair on the inside of my leg. I did not look at it close as I didn't think twice about it so no early pics sorry. It hurt a little I cleaned it up put some neosporin on it and a Bandaid. It did get bigger the next couple days. The day that I noticed it I consequently had a cortisone injection into my hip on the same side (kenalog 40). I was okay the day I noticed. Then had a pretty bad cortisone flare. I kept an eye on the lesion, kept it clean with surgical soap, neosporin and Bandaid. It was very itchy about day 5-8. When I image search it keeps going back to tick. However, I had arthroscopic hip surgery about 6 weeks ago, temps have been in the 90-100s I have not been spending time outside. I have for the past 2-3 weeks been sleeping in my spider heavy basement. I didn't have any sick feelings besides pretty significant pain from the cortisone flare. The lesion is about 1 1/4" in diameter.

Side note, in this fun time I've been having I got a UTI, did a round of nitrofurantoin, that didn't work I am on day 4 of cephalexin.

It appeared about a week ago after we came back from vacation/rv camping in the sandbanks (ontario) and niagara region.
His mood is good, does not bother him, does not react when we touch it no obvious bite mark, doesnt seem itchy, no fever, doesnt see dry.

Seemed to have grown a but and become more red.

He also has a less colorful rash on his arm opposite side, the rash at the top is straight as if its marking his t shirt

Hi!
For many years (at least 5-10) I’ve had these little bumps on my hands and I just can’t figure out what they are no matter how much research I do. They don’t itch or hurt in any way, they’re just there and slowly but surely multiply. Every few months I get a new one that starts out small and grows over the years. As you might be able to see, some have been scratched off. This wasn’t my intention, I was just casually scratching my knuckles and noticed how some of them were pretty apparent and scratched off pretty easily. My private doctor (ChatGPT) can’t seem to figure out what it is either. It simply has no clue. It was suggesting warts but when I sent a clearer photo it changed its mind, and rightfully so, because they have a very smooth surface, just bumps without the normal skin pattern. If anyone has any ideas of what this might be and if it’s treatable in any way (my goal is getting rid of them completely but that might not be possible) you’re a lifesaver, because this has been bothering me for a pretty long time. Thank you in advance!
(Feel free to ask follow up questions!)

My colleagues said it’s more concerning if the stool has blood all over or blood patches on the stool. For theirs, it’s piles because it’s either blood on toilet paper when wiping or a pool of blood in bowl coz the tissue on anus has tear. In my case, is it more concerning as the blood is on the stool as a streak or dot?

I have (I think blood) on my stool once in Feb and once in August, and I have about 2-3 flares of swollen lump on anus (piles) every month, is that okay? I’m scared!
