Well come to HCM
I really appreciate your concern, I had gone through the history given here and it seems to be chronic itching, may be eczema
, but it can not be this much chronic like 10 years, looking to this it could be functional pruritic condition, You can try Hydroxyzine
tablet three times in day.
If the worm infestation is not being ruled out then better to rule this out, I would suggest to give try with Mebendazole
100 mg once in day repeat the dose every one for consecutive three weeks (One tablet once in week )
hope this information helps.
