I feel for you. I have been suffering this biting nightmare for 2 years now. My face gets bitten badly if I kiss my kids who constantly roll around on the floor. I don't see an end to the nightmare and I can't believe this is happening to me. I do have some ideas how to sleep at night but its a long process. I've poisoned my house to the point that I have stopped poisoning although the temptation is always there. I just don't want my kids to end up sterile or with learning disabilities or with cancer or whatever. It's just not healthy. Best of luck dealing with it and you are NOT alone. Folks who suggest its allergies or whatever just don't understand. Feel free to work with me in finding solutions. I just think there should be a worldwide forum to discuss these things.
Just saw a post from a young woman who says the Dr. gave her a prescription of Clyndmycin and it stopped the itching for four years!!
I take an antihistamine every night before bed - otherwise I can't sleep with all the itching!
Please see: Invisible Bugs Crawling on my Skin on this forum.
There are too many things to try to list here.
Have you tried some anti histamines?
See: Invisible Bugs Crawling on my skin.... lots of ideas to try.
Tea tree oil works for some.
If you have checked the other pages/posts similar to yours, you will see that there are thousands of people suffering from this itch.
It could be the detergent, shampoo or soap that you are using. Hopefully, that's the answer.
Otherwise, you are one of many who have Morgellons or something similar.
I, too, have been itching for 7 years. Will be 8 years this October, 2013. Mine started with a bottle-nosed kissing bug bite on my back.
I have been to dermatologists who laughed at me, diagnosed it as eczema, and one gave me a shot of lidocaine and ushered me out of his office. I was itching horribly before I left the building.
I sincerely hope that your 7 year itch is not the same as mine. (No cure, yet.)
Wishing you the best
