I was getting sharp pains in my right ear &
Probable reaction to Amoxicillin
Hello and welcome to Ask A Doctor service.
I have reviewed your query and photos and here is my advice.
As per your description, this seems to be allergic rash to Amoxicillin, as it started after its use. We can try discontinuing Amoxicillin and observe if it gets better.
Second diagnosis that seems likely is Shingles rash - its extending in a dermatome and causing pain. Does rash have fluid filled in it? Triamcinolone may make it worse.
Check with your nurse or doctor if she agrees with the recommendation.
Hope this helps. Let me know if I can assist you further.
