Head a headache for 2days. sharp pains sometimes when i move. feel bit light headed. tired. and felt sick with it last night. should i go doctors. ?

Your call: Doesn't sound like you have anything terrible going on, but i don't know if you have any other symptoms or chronic medical conditions that put you at higher risk. A few causes might be dehydration, stress, diet (e g caffeine, blood sugar), sleep issues, viral infection (e g flu, cold), sinus infection, etc... Would rest, hydrate, take otc meds, and see a doc if fever over 101 or symptoms linger.
