Pins inserting pain frm nose toforehead.

Dear Doctors, My father was earlier facing an sinus problem and he started taking precautions on everything and gracefully he has recovered from it, But during this course he started having a pain in his right side of forehead starting from nose. Earlier this pain was normal but its increasing gradually and now the condition is force air, while eating, brushing, looking down and some tile sitting idle this starts and it's very painful. Our ENT consultant said its not because of sinus there is some nerve inside brain which is slightly pressed and practically no solution for the same, thus would like to know is there any partial or full solutions? I knw surgery is risky and we don't want to opt for that. Pllz suggest!
