Why does sweating cause an itchy red rash? (photo)

Doctor's Answers 1

Thank you for your question. There are various causes of itchy bumpy rashes and these include eczema, bite reaction and scabies.

Heat and sweat can aggravate eczema and make the skin more itchy. Excessive scratching can also make the rash worse.

However, if the rashes are still persistent, it will be good to see your doctor or dermatologist again to re-evaluate the rash to endure a proper diagnosis and treatment.

Does facial laser treatment trigger psoriasis?

Thanks for the question. If you have a diagnosis of psoriasis, there is a possibility that certain treatments can aggravate it. With psoriasis, damage or injury to the skin can cause psoriasis to develop at the site of the injury. This is know as the Koebner phenomenon. Therefore, you do have to take care that the treatment is gentle and does not cause any trauma or damage to the skin. Likewise, for eczema, the skin is sensitive and more prone to external insults, so you should avoid treatment if the facial skin is still red or irritated as this can be more easily aggravate by treatment.

What could be cause of my skin rash after giving birth?

Thanks for the very clear history and photographs. The red rash looks like a bruise and this is likely to be due to excessive pressure over the area, aggravated by the compression from the stripes which squeezes the enclosed areas. This will typically take 1 to 2 weeks to resolve. Blood tests are usually done to rule out underlying conditions like low platelets which may lead to increased susceptibilty to bleeding. I assume these tests were done and were normal. I would suggest wearing leotards without this stripe pattern so that there will not be added pressure to the skin.
