I had my top and bottom wisdom tooth removed 5 days ago, but still have pain after where the teeth used to be which causes headaches especially when i talk a lot or eat. it goes away after taking medicines. is pain normal even after 5 days?

Wisdom tooth extraction is a minor surgery and depending on the complexity of the extraction it is not uncommon to have post operative pain, sometimes longer than a week. Anti-inflammatory medications should get you through this healing period.

Four teeth extracted at one time ,especially if bone had to be removed would result in pain and discomfort. Pain and swelling could last more than five days, even 10 or more depending on healing process. Follow all post extraction orders and go back to dentist in at least 10 days. Keep area clean and don't let food or debris accumulate in extraction holes, flush out any particles.

Post surgical pain, from any type of surgery, may last as long as 2 weeks. At your stage in healing OTC nSaids should be helpful. I'm sure you Oral Surgeon provided you with written post-operative instructions. If following them does not provide relief, call the Surgeon (S)he is responsible for your post-op care and will gladly help.
