For the past couple months Iíve had twitches all over my body that come and go everyday. They drive me crazy because I donít know what they are. However, Iím feeling this lower left back pain now around where it would be the kidney area. Now Iím terrified that this all can mean that I have horrible kidney problems. I am terrified. Iím a 17 year old male. Anyone? (Iím having a checkup in a week)
