23rd surgery, 2nd day post op. Face mainly and arms hot & flushed. Anesthetic reaction? Antibiotics reaction? Hematoma again?:(?

I was discharged yesterday, after having capsulectomy on right breast and new implants to replace pips. My face is constantly hot and flushed,so are my arms. Could this be due to a reaction from the antibiotics they put me on, amoxicillin or even the general anaesthetic? Or couldn't be hemotoma /infection brewing? :( doesn't seem to of swelled like it did last time with hemotoma so preying it just a reaction? advice appreciated [RS bleep] the hospital said to take piriton and call back if same in 2 days?! :/
