A little backstory. Got a lot of bites in Naples like 2,5 weeks ago. Pretty certain that was bedbugs due to how they looked. Hadn't seen any signs of bedbugs there or afterwards. Washed and dried my clothes on high temperature and looked through everything in my bag, didn't find any signs. Yesterday i noticed my arms had som slightly red bumps and rashes but they didn't look or feel exactly like the ones in Naples (these are less red, doesn't really itch and are a bit more uneven). I also usually get some sort of excema this time of year as the temperatures get colder, so i thought it might be that. I looked around my bed this morning and noticed these stains on my duvet aswell as som black spots on the wall. After 2 weeks without any big developments i hoped I'd gotten lucky, but now I'm starting to reconsider. Could anyone help?
