after effects of flu?

Hi, i'm just over a bout of the flu, it lasted 15 days and i had swollen glands and chest infection also, i was on anti-biotics also.  I'm back at work this week and am tired a lot and have sore neck and back, sore sinus on one side (not blocked) and tight scalp muscles and dizzy feeling, i went to doctor and i don't have temperature and was advised to keep on over the counter pain killers.  The dizzyness unnerves me quite a bit and was wondering if these are after effects of a bad flu?  any advice or help would be greatly appreciated.  ps, get well everyone!

These can be symptoms of a viral infection that takes several days to resolve.  They could also be due to a sinus infection, which can cause the same thing.  However they may not go away without antibiotics.  I would watch and see how you are doing over the next several days.  If you are not gradually improving, call your doctor and report your continued symptoms.  Most likely, this will result in another course of antibiotics.
