Ive been having a slight headache yesterday night , i took a painkiller (panadol) which wasnt effective at all, at morning it got worse, im already having a tooth infection which went all up to the roots which may have been the cause the of headache, but as per my doctors suggestion i took (dolonex) which again did not make any change in the pain. So i decided to steam because i also have sinus problems since childhood., The problem now is i am having unbearable headache after doing the steaming
