Since then this is what has been happening.
Not saying to try this but it helped a little.
Last week i couldnt stand it anymore. Im not sure if its scabies but i do feel like something is crawling all over me, im convinced its some kind of mite. I can look at the spot where its crawling but there is never anything there.
So i used vinegar mixed 50/50 with water and i poured it over my body and left it for about 10 minutes then rinsed in the shower. It was interesting to see that certain parts of by body got red reacting to the vinegar and those were the itching parts..
I did that for 3 days and it helped a little. But the problem now was that they were moving now lower. So i triend the lice shampoo but read that you need 5% permathrin but the lice shampoos only had 1% so the smell just made me feel sick. I did buy the spray and sprayed my chairs and bedding. not sure if it helped since ive not seen one bug in my bedroom but it couldnt hurt.
So now its moved to my groin area and my face and scalp itches and my eyelashes itch. I still feel like something is crawling on me even as i type this...when im less preoccupied i feel them more. I even spent the nite at my friends house and i still had the crawling feeling all nite.
So i bought some tea tree oil 100% and used a small cotton rag and have been applying it once a day to my body. it seems like it is helping , but dont put it on your eyelashes, i learnt the hardway..eyebrows are fine. It smells a little like lemon and kerosene mixed. I will let you know in a few days if its helping.
I have a strong feeling its scabies or some kind of mite...i did house site about 2 weeks before i got symptoms so thats the only thing i can blame..
good luck and update me if you can
