Sorry for late reply and inconvenience.
Thanks for all this additional information.
I understand your concern.
Well as you describe, you should continue soaking your thumb in warm water and add some antiseptic solution like betadine solution.
And afterward, apply OTC 1% hydrocortisone cream mixed with bacitracin ointment twice a day.
Take OTC Motrin and Claritin for a few days.
You should hydrate yourself with warm liquids.
You should start a multivitamin supplement and vitamin C lozenges.
It may take a week to resolve and sometimes a few days more.
I apologize for not able to give you a prescription of oral and topical antibiotics.
If your symptoms will persist then see your doctor for further evaluation and management.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
