Hello.
Thank you for asking at HCM.
Since you are having itching without hives, the causes can be non0allergic, too. Most common causes are dry skin and micronutrient (vitamins & minerals) deficiencies but other causes can be also there like
chronic liver disease,
chronic kidney disease, thyroid disorders, some drugs, etc.
Hence I would suggest you to regularly apply moisturizers over body and take nutritional supplements containing especially vitamin E, vitamin A, zinc & selenium. Please try to wear loose, cotton clothes if possible and avoid woolen, tight clothing. Please try to avoid activities causing
excessive sweating.
If this does not help, I would suggest you to go for investigations like CBC, ESR,
serum creatinine, blood urea,
prothrombin time, serum proteins including albumin, thyroid function, urinalysis, etc after consulting your doctor.
I hope this will be helpful to you.
Wish you the best of the health.
Regards.
