the feeling of 'drugged up/light headedness' ?

I had viral meningitis a year ago, diagnosed by sample of CF. I was discharged and returned to work 1 month after hospital admission. Although i was feeling ok, i have had intermittant headaches which have recently become 1 long dull ache with the occasional use of painkillers required. I have also bean to be tired and have the feeling of 'drugged up/light headedness' with dizzyness thrown in for good measure. More recently my bach has began acheing at the area of where the sample was taken. (it did taje them 3 attempts to get the cf) Im looking for reasurance that its not the meningitis trying to make a come back. I never had a rash in relation to the meningitis
