Over the last few months i have been having burning in my head, It feels like something hot being put onto my head for a few seconds at a time always in the same place and always quite painful. however now the burning seems to be lasting alot longer and I am begining to worry. I get alot of headaches nearly always near the site of the burning which can puy me in a darkened room for a day or two at a time.   I do not drink smoke and where possible abstain from caffine. please do you have any idea as to what may be causeing this and how i can help the symptoms.?
