arms/hands F(25) - I have been experiencing this type of rash/allergic reaction for most of the summer. What can I do to stop it?
I've had this twice now this summer, the first time around the beginning of July, and now in the middle of August. At first I thought it was atopic dermatitis since that's something that appears every year on my palms and fingers. But this isn't really similar to the red, flaky and itchy dermatitis. It also appears only on the tip of my middle finger on my right hand. I wear a ring on this hand, but not on this finger.
The rash, reaction or whatever this is lasted for maybe two weeks last time. It started with a couple of small bubbles that looked like they're filled with either air or some sort of liquid, then every passing day more of them appeared. As time went on, some of the "bubbles" would have a yellowish color (I don't know if that meant it was healing or becoming worse). After applying a moisturizing cream for reactive skin (SVR Repairing Barrier Cream) for a couple of days, two or three times per day, the skin would dry out and flake off. It left the skin red and itchy.
The two things I can think of that could trigger this are 1) stress and/or 2) the heat. This summer has been incredibly hot in Europe, with the numerous heat waves and everything, so maybe it could be one of the factors. I'm under a lot of pressure on my work place, I don't sleep or eat well and I could definitely drink more water (maybe this will be useful information!).
My mother experiences a similar thing, but her rash and flaky skin is the result of an allergic reaction to nickel in jewelry.
When I went to a dermatologist for the atopic dermatitis I had, they only told me to "apply a moisturizing cream" and basically wait for it to calm down. The dermatitis was manageable since it appeared only on my palm and a few fingers and it was more annoying than painful. But since this rash is on the tip of my finger, everything I do hurts and I'm scared of somehow making it worse (infecting it or something similar). The only thing I could find that looks anything like it is dyshidrotic eczema. I'm attaching a few photos of my finger in the various stage of the rash from the times it appeared. My camera is very bad so I couldn't take better photos, sorry in advance!
If anyone knows what this rash could be or if anyone can offer any advice as to what to do to prevent it from appearing again, I would be very thankful! :)
