<human>: I feel things moving and biting me in my pubic hair but the doctor can see no infestation. I have taken thread worm tablets for 3 times but still have itching around the anus as well. I also have head lice and itching and biting in my eye brows and wriggling in my tear ducks. I feel infested but, apart from a few head lice eggs around the back of the ears nobody can find anything and I m going mad from having them crawling on me. I also feel them wriggling under my waist band. I have not been sexually active in 10 years so it s not crabs either. Please can you help?
<bot>: HelloThanks for the query. Head lice are very difficult to eradicate until full course is not taken. Beside full course personal hygiene is very important. In this type of condition I usually prescribe permethrin 12 mg / day for 7 days. I also prescribe albendazole 400 mg/ day for next 3 days. Local application of permethrin soap twice in day for almost 10 days. After 10 days I recommend gamma benzene as a local application for three days. You also require dermatitis treatment around anus. In my opinion consult a dermatologist and get his opinion for anal treatment. Good luck.
