Why do I get rashes everyday that comes and goes in a few hours?

Doctor's Answers 1

These rashes sound quite bothersome to you. From what you have described, they seem to be hives, also known as urticaria. They will suddenly appear, be very itchy, sometimes associated with a burning sensation, and then disappear in a few hours, usually within the same day. Please try your best not to scratch them as the rashes may worsen with excessive scratching.

There may be a trigger at times shortly before the onset of these rashes. The most common triggers are a recent infection (cough/ flu/ fever), allergy to a certain medication or food. However in most situations, patients are unable to recall any particular trigger.

Hives can be unbearably itchy, and anti histamines can help to alleviate the itch. If the hives are recur on a regular basis, it is best to seek a dermatologist's help as blood tests may be needed.

If there is difficulty breathing, funny wheezing noises from the throat, swollen eyelids or lips when hives occur, you will need to go to the emergency department as soon as possible as it means that your airway may be blocked.

I hope that your condition improves soon, take care!

Warm regards,

How do I know if I’m having steroid withdrawal symptoms?

Thank you for posting a question. This is a complex question, which warrants proper questioning and examination by a qualified doctor. Any answer we give here will be difficult to answer your question with proper justice. Depending on your weight, 20mg of prednisolone is usually considered low dose and it is usually not expected to have these side effects especially when the course is so short as well. (perhaps you can consider to see a doctor to check if you have other medical problems) Most of your symptoms are non specific, and as such answers will probably be non specific as well.

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.
