Hi...
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns...
As per your complain it seems like you have side effects of antibiotic Flucoxacillin and the symptoms seems of
lightheadedness, headache and sickness seems to be due to it while throbbing in ear can be due to the abscess causing
radiating pain to ear..
You should stop taking Flucoxacillin and take anti-allergic medication like benadryl to relieve the allergy symptoms..
You can take another antibiotic that does not belong to penicillin group like Cephelexin,
ciprofloxacin etc.
Take painkiller like Diclofenac potassium for relieving ear throbbing..
You should also clean the abscess with an antiseptic solution and apply a
triple antibiotic ointment and a steroid ointment over it..
In case if it does not shows signs of resolution in 3 to 4 days consult a Physician and he can do an
incision and drainage to remove the infected pus along with antibiotics and painkillers..
Hope this information helps..
Thanks and regards.
