Hello,
Eczema can present differently at times so you may not rule this out altogether. Try using a thick moisturizing cream like Cetaphyl or Eucerin - the cream in a jar; not the lotion. Apply this a couple of times daily and avoid soap. You can use Lubriderm or Cetaphyl cleanser instead.
Are there any white centers to the red rings? If so it could be ringworm, which is not actually a worm at all, but a fungus which can be treated with antifungal medication over the counter. Scabies is another condition that causes an
itchy rash, but usually this is raised and often noticed between the fingers. It is caused by a mite and is transferred person to person.
If you don't get relief, you may need to see a dermatologist when the rash is present so it can be diagnosed properly. If you establish yourself as a patient with a dermatologist, they will usually work you in on short notice when you need to present at a particular time, such as when the rash appears.
Best wishes.
