Hello,
Thank you for posting on HCM.
From your description, it seems you might have got
scabies. Scabies is an infestation by mite which causes itchy bumps and it spreads through direct contact with infected person or clothing etc.
The treatment is pretty simple. You will be prescribed some oral medications like
Ivermectin in two doses with a gap of 10-15 days and will also be advised single application of a cream containing Permethrin 5%, right from neck downwards to cover whole body and to be washed after 6-8 hours. All of your family members and your girlfriend should ideally be treated in same way.
Apart from this you might be advised creams containing mild
steroid and antibiotic to take care of skin lesions.
Maintain proper hygiene and launder all your clothing and bedding properly.
Avoid sharing of towel/napkins and other toiletries.
I hope this will resolve your queries and wish you best of health.
thank you,
Dr Hardiik Pitroda
