That is heartbreaking. I could be wrong but I'm from the south and grew up on a farm. It looks like the creeping eruption disease caused by hookworm larvae. They are nematodes most likely coming from untreated cotton clothes, made in China especially. I have battled them most of the year and they are everywhere but certain people like me are allergic to them. I threw away all clothes made in China and wear jeans made in this country nad shirts that are 0 to low % of cotton. The vet meds make them crawl and I have seen them rocket out of my hair I guess exploding from eprinex pour on. They will get in sheets and the bed mattress.
I also had flukes in my sinuses nad these hookworms in my ears. Doctors won't tell but they know because my ENT took samples and gave me eye and ear drops that have worked well along with ivermectin and fenbendazole. You can not rely on doctors either. *One important thing is to Not give or take too much of the vet meds. I ended up in the hospital with Toxic metabolic encephalopathy which is focal seizures. Check your clothes. I got a lint remover tape version and do that to everything I wear because I live in an apartment with one washer dryer to 6 rooms. I cut the ivermectin down to 1ml once or twice a week which equals to 10mg/1cc or ml with the injectable and I swallow it bc i am not using a shot on myself. The horse paste I follow the weights on the syringe. Fenbendazole I take that almost every day 222mg bc that doesn't seem to have side effect. For the rashes Psoriasis ointment with coal tar works and stops itching, vinegar works but burns too. I also find that working out and staying active helps with it all. I am not sure what the green things are some other type of worm maybe someone else can id those. Hope that helps, any questions let me know.
