It sounds like you are having an allergic reaction
. It is possible that this may be to the hydrocodone
you were taking for pain or possibly to an another recent medication such as anesthestic or pain medicine given prior to your tooth being pulled out. The antihistamine benadryl
will work to decrease the allergic reaction. Since you have also developed a rash
you may want to consider treatment with a stronger antiinflammatory medication such as a steroid
pill for a short course or a steroid cream. Continue the the Benadryl. The reaction seems to be subsiding but keep a close eye on it. Wishing you good health.
