Headache for 5 days continuously.

Hello all, I have been having headaches continuously for 5 days now. It started on 3rd evening and was there till 4th afternoon and I couldn't sleep properly. Then it started again on 5th evening and lasted till the end of the day. On 6th it started in the evening and went away. From 7th morning till now (8th night) i have it continuously. The pain is a combination of pressure, throbbing and tightening. It is there on one side at times and on both sides. I also have neck pain, temple pain and forehead pain. I was out in the sun for a week before this (from 25th August to 31st August). I Do not smoke. I took ibuprofen + caffeine tablet yesterday and it worked for a while, and the headache came back after a few hours. Is this a tension headache or a migraine? What can I do to get rid of it or prevent it.
