For the past couple months I’ve had twitches all over my body that come and go everyday. They drive me crazy because I don’t know what they are. However, I’m feeling this lower left back pain now around where it would be the kidney area. Now I’m terrified that this all can mean that I have horrible kidney problems. I am terrified. I’m a 17 year old male. Anyone? (I’m having a checkup in a week)
