Hi..
Can understand your concern..
As per your complain it seems that the swelling on lips and small bumps under the tongue has occurred as a side effect of taking the antibioticswhich you have taken for
tooth infection and pain..
It has occurred as a side effect of
amoxicillin and will take some time to disappear as the medicine is now withdrawn..
You can take allegra or
benadryl which are antihistamines and will help in reducing swelling..
In case of pain anti inflammatory painkiller like
Ibuprofen can be taken..
Salt water rinses can be helpful..
Gargle with 1:1 solution of benadryl and
milk of magnesia will help..
Sucking ice pops will be helpful..
Apply numbing gel on the sores like oragel for relief during eating..
Avoid hot and spicy food..
Do not suck or put pressure on lips..
Ice packs over the lips will help in reducing swelling..
Hope this information helps..
