Hello. Im having headache from past four days straight. I also have a history maxillary sinusitis. I take anti depressants as those are consulted by my doctor back home. I study outside now so that is why do not have my contact with doctor. About my headache, im also feeling this pain in my ears. I take the paracetamol daily but still I feel nothing positive at all. What are the things I need to take into consideration as soon as I would have to?
