Have you tried taking an analgesic? You could try acetaminophen, aspirin, or ibuprofen. If the pain is really bad try taking a combination pain killer that also contains codeine - ask your pharmacist for advice.
Headache is a reported side effect of sulfamethoxazole.
See your doctor if the pain is unbearable or you experience other symptoms such as slurred speech, fever and vomiting, visual changes or stiff neck. free discount card
