What Causes Headache, Sore Throat, Pain In Back, Legs And Eyes?

I have a headache sorethroat back pain leg pain eyes hurt? hips hurt and on accutane?
I know this drug is dangerous but I don't know if how i'm feeling could be related.
I woke up feeling not myself and kind of nauseous but im not anymore. i also felt like my eyes were hurting like when u cross your eyes 2 many times and they get sore which i still have. later around 3:30 i got a headache and some back pain. about 2 hours ago my legs started feeling sore and its very weird but it feels like my hips r sore especially on the right side. My face feels really hot but idk if i have a fever. my neck hurt but that went away. i just started my 3 rd week of accutane and only got i headache b4 that was bad but i wasnt sore and it went away the next day. so im kinda scared if the accutane is causing this or if it sounds like meningitis? sorry about the bad grammer but i don't feel good at all.
