How Can Persisting Knee Pain While Bending Be Treated?

Hi, I work out on a daily basis but have a very severe pain in my knees now, it started out as just a minor pain but got worse and worse the more i exercised I thought it was just a minor pain that would go away if I take it easy with the leg exercises but even after a week of resting the pain didn’t get any better, the pain only happens when i bend my knees for example a squat i can run fine, is this something that would require surgery?
