Suggest Treatment For Oat Tree Mite Bites
Change clothes, take Zyrtec twice/day.
Detailed Answer:
I am so sorry you are having this problem! I know that your area of the country is having a very bad problem with Oat Tree Mites right now, but these mites do not stay in the skin. After they bite they drop off rather than burrowing in the skin and popping out.
The usual treatment of the itchy rash is calamine lotion, and take an oral antihistamine such as Zyrtec. Zyretec 10 mg can be taken twice a day to help control the itching. You can get this medicine (generic is ceterizine) at any drug store. Some allergists recommend using it up to 4 times a day, but best to start with 1 pill twice a day and see how you do with that as it can be sedating.
If this does not work adequately, you may need a topical steroid or even a brief course of an oral corticosteroid to control the painful itching. You may need to see a dermatologist but if you can't get in then start with your primary care doctor.
Be sure to cover yourself well when going out and change clothes immediately when you come in from outside.
I hope this information helps and that you feel better soon!
