There are many different reasons that people can develop dry and itchy skin rashes. Although all rashes may look the same to the untrained eye, they actually have slightly different qualities depending on their cause. A picture of the affected area and some basic information is usually enough for a trained doctor to find the likely cause of a rash.
Perhaps the most common cause of rashes is eczema. Eczema – which is also called “dermatitis” – is a general term that covers many different skin conditions. Because there are so many different possible kinds of eczema, it’s important to give the doctor some additional information. This information will help them figure out the type of eczema you have.
In addition to a picture of your rash, provide your remote doctor with a list is anything unusual you’ve been in contact with lately. This list will help the doctor identify any allergens or irritants that could be causing your eczema. If the doctor spots any known allergens, then it’s possible that those allergens are behind your breakout.
Suspected cases of allergy-related eczema should be followed by a blood allergy test. This test can be done by your primary doctor. An allergy test is an important next step because most people are allergic to more than one thing. If you don’t know all your allergens, it can be difficult to prevent exposure and stop your symptoms. If you want to learn more about how allergens work, check out this video.
Another possibility is psoriasis. Most cases of psoriasis can be recognized by the white, scaly patches that appear on top of the rash. Psoriasis also runs in the family, so your chance of getting it is higher if one or more of your family members has it.
There is no cure for psoriasis, but the good news is that most cases are pretty easy to treat. The majority of cases can be treated using creams alone. Psoriasis is usually diagnosed visually, so it’s easy for a remote doctor to confirm a suspected case and recommend appropriate next steps.
While it’s never fun to deal with an uncomfortable and itchy rash, the good news is that a lot of cases are pretty easy to treat. Having a remote doctor take a quick look at your rash is often all you need to get a diagnosis and start taking steps to feel better!
