body ache and feeling feverish....is it ok??

Have been oil pulling religiously twice a day with sesame oil and had seen some improvement in my dental health. Now since saturday, have switched to extra virgin coconut oil ( do not know wt type was sesame oil, the bottle just said pure sesame oil). And, today, have been having body ache and feeling feverish since afternoon....nothing much but just tired and achy. I have read tht oil pulling does tht sometimes...so is it due to my changing oils?? I do hope it passes soon....has anybodu else experienced the same??
