Welcome to Just Answer.
When did it start?
Is there any rash?
Is there any previous disease?
Thank you.

3 weeks ago or so. no rash. no disease.

Thank you for the information,
The causes of itching can be few.
The common cause is allergy, dermatitis.
Dry skin or seborrhea or increased sweating can also be factor.
Sometimes iron deficiency, liver or kidney disease can also cause itching without an apparent rash.
I would advise to get an examination by doctor.
Doctor can then decide about tests after physical examination.
Antihistamine like zyrtec would help in itching.
Diphenhydramine cream can be applied.
I hope this information helps.
I will be happy to assist, if you need any clarification.
Please feel free for any follow up query.
