Crying when feeding after a fever. Less?

On 25 jan My baby three month old 6.2 kg was having fever and cough us crying after feed and after sleep. My mom and me also have fever and cough. Doctor gave taxim o cefixime oral suspension, paracetamol flucold drops, levosalbutamol sulphate, ambroxol hydrochloride guaiphenesin drops. One day his fever was 99 F either more or less fluctuating. Next day 26 jan his temperature now is sometimes 96 -98 range. Mostly 97. Is this too low?? Two days he ate feed every two hourly and mostly slept. Third day today he drank but one feed ge refused to feed on my breast. So gave formula. After that two feed he drank. Again now hea not ready to feed on breast nor formula , crying if we force . Hes sleepier than normal days is it ok?? Paracetamol and antibiotics is five days couse. Shud i take even if temperature less??
