Hi while exercising i got a sudden sharp headache at the back of my head. it's been a few days and also moved to the temples and above my eyes. can you advise please.

Lets try Paracetamol: Unless you have some anxiety or tension in your daily routine, it should settle down with a short course of paracetamol. You can take 500 or 650 mg dose and repeat it once 6 hours later unless the pain is gone. It should settle down in 4-5 days. If it is getting worse despite paracetamol, then you should get a check up from your family doctor.
