Itchy skin without any rash can be due to dermatitis, lice, scabies and hives, internal diseases like liver and kidney disorders, diabetes, iron deficiency anemia, irritation and allergic reactions to chemicals, wool, soaps, cosmetics and certain foods.
Wash the areas and wear cotton garments. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps.
For mild-moderate symptoms a weak steroid may be used which is available under a dermatologist’s guidance.
In case the symptoms persist then consult a dermatologist in that case and get systemic infections ruled out.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
You just described me!! I feel for you!! Please tell me if you found any relief? It's agony to be trapped inside this itching body. I describe this torture like my blood itches w/ random pin prick sensations. Struggling off & on with this over the past years it is increasingly getting worse. I have done the whole nine yards...elimination diets, supplements, acupuncture, exercise, no dyes, perfumes, etc,etc. I have spoken to Both holistic & western medical professionals ( I promise you they would be more interested if They were the ones ITCHING)! I have been told to take anti psychotic medicines (frankly that offends me) I want to live my life / not be drugged. My saline implants ruptured & I'm scheduled to have them replaced but am suspicious if they're to blame?? I would happily have them removed if, I can regain my quality of life... Thoughts & comments greatly appreciated. I pray you found help!
