Quick question

Hey I wanted 2 ask if ms symptoms can feel like the flu. I woke up this morning feeling totally floored, weak, headache, achy muscles and horrendous burning nerve pain from the pelvis down. This is a usual pain 4 me but not as bad. Started on pregabalin on thurs but yet 2 take effect. I guess the question is am I getting a viral thing or cud this b a flare up of whatever I have going on. Not such a quick question after all…
