Why when I swallow it fells like I am swallowing needles?

Infection? If this just started, get checked for strep throat, which needs to be treated within 10 days of the onset of symptoms to prevent complications. If you have had this for a while, see your doc, too, and find out why it hurts so much to swallow. You need to be seen in person by a doc who will examine you, order appropriate testing, treat you and/or refer you, if needed.
