Patient's Query

Hello doctor,

I am a 26-year-old female with no significant health history. I have anxiety, and I had hyperthyroidism in the past. I have had an itchy rash for over three months. It started as a small patch behind my left knee. It happened after having a ring shaped rash on my left thigh. I was treated for that with antifungal cream and it went away.

This new rash is completely different. I am extremely itchy to the point. It is interfering with my life. There is no obvious rash unless I have already scratched that area. I then get a bunch of small skin-colored bumps. Also, after scratching, I often get petechiae and bruising. The itch is everywhere but my face. I have been waking up wet from sweating even though my bedroom is fairly cold at night. A few times I have checked, I had a small fever of around 99.1 Fahrenheit. My doctor puts me on antihistamines (Benadryl at night, Claritin during the day) and steroid cream. It has not worked. She recently wrote me a prescription for Prednisone, but I am worried that a skin allergy just is not what I have.

I am currently taking Effexor 75 mg, Klonopin 0.5 mg when needed.


Welcome to icliniq.com.

You do have a bright red colored rash over the legs. Such rashes occur mostly as a response to allergies. Now allergies can be because of food (artificial colors) or even at times because of insect bites. The petechial patch on the shin is nothing but a result of excessive scratching of the skin. You must use a good preservative-free hydrating moisturizer (Cetaphil Restoraderm) in the morning. If the itching is severe enough, there is no harm in taking a short course of Prednisolone. Most importantly, get your blood workup (complete blood count) done. You can get back to me after the blood work is done.

Same symptoms don't mean you have the same problem. Consult a doctor now!
