My friend has been quite poorly the last few of days. He was feverish hot/cold spells, body aches, migraine-like headache, lack of appetite and feels giddy. Now it's more giddiness, headache and body aches. It started two days after he finished a weeks course of antibiotics. I'm just wondering if it all was possibly an allergic reaction?? I'm really curious about this since he won't be able to make it in to his regular doctor for two more weeks (in the UK the waiting for an appointment is a nightmare, and from what I've heard going is a waste of time anyways). If it's just an allergic reaction, I don't want to prod him into going to the ER, so any ideas??? Any info would be greatly appreciated.
I haven't been able to find out what antib's he was on, but I'm guessing it's something similar to Cephalexin since he was complaining about his urine being orangey (I had a similar issue with it).
