I am a 20 year old and just got diagnosed with MS this year. I take the med "Tecfidera". I've been having some form of influenza like twice since I started taking it (I assume it's influenza I don't really know) I just feel like it's taking longer for me to recover than usual and I feel like the symptoms are worse. I feel like total shit. Maybe it's just me being mad at this disease but I dont know. Can meds like tecfidera worsen symptoms in illnesses like these?
