Hi.. Thanks for the query.. It is clear that you have antibiotic induced allergy that has caused rashes and red bumps but now it also appears like there has been infection leading to fluid filled bumps.. You should consult an Emergency room and get evaluated.. They can advise you a script of antibiotics after checking for compatible antibiotics that will not cause allergic reaction and along with it topical application of antiseptic ointment after cleaning the bumps with antiseptic lotion can be advised.. To reduce allergy and rashes you can be advised anti allergics like Benadryl or Allegra along with a steroid shot for faster relief.. Do cool compresses over the rashes.. Hope this helps.. Regards.
