Hey guys. Im 4 days post op and ive actually had a nice revovery so far nothing too painful but last night i was getting a headache so i had 2 cocodemal and my antibiotic and went to sleep. Ive woken up with the headache had my 9am antibiotic, 2 cocodemal again and i feel sick! Like proper sick to the point i went to throw up but nothing come up… is this normal? Im already 4 days in and felt fine until now?
