Should I see doctor about pain in the middle of my chest and what could it be?

Yes. There are many causes of pain in the middle of the chest but the one that's on your mind (if you asked this question) is heart disease. So go see your doctor and make sure you're okay. If it's not serious, you'll feel better about it and if it is serious, you'll be glad you didn't wait.
