Hi wondering when on interferons how long you all continue to use painkillers before injecting… I’ve been on avonex since last September and always take paracetamol and ibpubrofen before injecting and then 4 hrs later forgot my second dose last night and woke up feeling crap hot cold headache!!..feel a bit rough today as awake a good couple of hrs!.. Just wondering if you all still take painkillers even if you’ve been on them a while!..I didn’t suffer with side effects as always taken something regularly…thanks Emma x
