What Causes Itchy Red Bumps All Over The Body?

Hi, I have been really itchy, having rough bumping skin, with small red dots all over. around the size of a pencil dot. its especially worse after I shower. its almost like getting sprayed with acid. its very uncomfortable and has been going on for years now. ive tried creams ointments, lotions, powders, and taking Benadryl or allegra and nothing really helps. its worse rite after a shower but never really goes away. I would greatly and appreciate any suggestions.

Hello,

Itchy bumps on your body are due to causes like:
• Any bug or insect bite that was toxic enough to cause generalized allergic reaction.
• It can also be due to mite infestation causing scabies.
• It can be due to contact dermatitis that is an allergic reaction which occurs when skin comes in contact with certain agents that your body is allergic to like skin cosmetics, detergents, soaps, fragrances leather, latex, poison ivy, etc.
• Folliculitis or generalized hair follicle infection caused by staphylococcus bacteria leading to formation of painful bumps over different parts of the body.
• Another cause can be food allergy or side effect of medicines.

I would suggest you to consult an allergist and get evaluated and a thorough clinical evaluation and investigations like blood tests and microscopic examination of the scrapings from bumps can help in diagnosis and treatment can be done accordingly. In case if it is an allergic reaction anti-allergics like Allegra or Benadryl, steroids and also injection of steroid for faster resolution along with steroid ointment and cool compresses over red bumps can help. In case of scabies oral Ivermectin and topical Permethrin lotion can help in relief.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Honey Arora
