Why do I have rashes with blisters and spots on my skin?

Hello,

Welcome to icliniq.com.

I completely understand your concern and how uncomfortable this situation can be.

Based on the picture (attachment removed to protect the patient’s identity) and your symptoms, these spots are due to insect bite irritant dermatitis, which means an insect bite has caused a local reaction in your skin. This is a very common condition that we often see in patients, especially those with sensitive skin.

The way the spots are close together, the dark or purple mark in the center, and the burning, pricking, and occasional pain you feel are typical of insect bite dermatitis. The two spots with blisters show a strong reaction to the bite, while the ones with a purple center are due to minor bleeding or skin damage at the bite site. This can happen after bites from insects such as mosquitoes, bed bugs, ants, or spiders.

It is a good sign that you do not have a fever, spreading redness, pus, or any previous illness. Since it has been about one week, this is now the normal healing stage of insect bites. Sometimes these bites cause pain or burning rather than just itching, especially when the skin reaction is deeper. Overall, although this is uncomfortable, it is not dangerous.

The only condition that needed to be ruled out in your case is scabies, in which there is intense itching, especially at night, in the armpits, fingers, and genital area, or itching that gets worse when you are warm or in bed. Along with this, itchy bumps or rashes appear on other parts of the body, such as between the fingers, on the wrists, elbows, waistline, or around the ankles. Scabies also has a positive family history, which is not present in your case, so this rules out scabies from the equation.

This is irritant insect contact dermatitis. At this stage, proper care and treatment are important to prevent infection or scarring. Avoid scratching or squeezing the lesions. I am providing you with instructions along with medicines that are available.

• Keep the area clean and dry.

• Wash daily with lukewarm water, pat dry, and apply Fusidic acid with Betamethasone cream on the affected area during the day and night for one week only to help it heal faster.

• Take a Cetirizine 10 mg tablet at bedtime for itching.

• Take Diclofenac with Serratiopeptidase 50-milligram and 10-milligram tablets during the day and night for three days only to reduce pain and swelling.

• Please avoid applying turmeric, Povidone iodine, or any self-medication to prevent added infection and to allow faster healing.

• These lesions usually heal within seven to ten days.

• Also, place your bed mattress in direct sunlight to help reduce insects, as heat can kill insects such as bedbugs and mites.

• If possible, keep the mattress under strong sunlight for four to six hours and expose both sides.

• Wash bed sheets, pillow covers, and blankets in hot water and dry them in sunlight or a hot dryer.

• Vacuum the mattress thoroughly, especially along seams and corners, to help prevent this situation in the future.
