Dear friend, welcome and thanks for entrusting your query here at HCM !
Did the problem begin after antibiotic course?
Are there weals (red, raised itchy lesions) over the skin?
Is there yellow jaundice?
First possibility is an allergic reaction
See if eosinophil count
in the blood test
You will need an anti-allergic like cetrizine
and a steroid
to tackle the allergy.
Cause should be removed (e.g. antibiotic which caused to be stopped)
Please see your doctor to consider these possibilities.
If not allergy, jaundice can cause itching sometimes.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries.
Thank you and Good luck !
