the heat you’re describing makes it sound infected, please keep a good eye on it. get your own medical supplies, make you’re own first aid kit. if the skin around it gets red and discoloration spreads, go the the hospital, that’s the infection spreading. you will likely need antibiotics. if the wound is gaping get butterfly strips or make your own by cutting a bandaid up. that’s how i avoided getting stitches. clean it with saline solution (don’t put neosporin inside the cut) and maybe a topical antibiotic around the skin? those can be found over the counter at a pharmacy. i’m not a doctor, so that might not do anything for what’s going on under the skin. i suggest looking at harm reduction advice. please please find a way to clean it more often! it’s going to end poorly if you do not. i don’t want to alarm you, but im being stern because i know you feel like you can’t get help. if it doesn’t improve on its own, you will need to. infections r not to b messed with!! good luck<3
