Hi, I'm a 25 year old female, 5'5 and 112 lbs. I have been experiencing very intense jolting, shooting pains in random places throughout my body on both sides, usually from the waist down. I have no idea what it is, but I do know that I also have SI joint pain, in which I experience the same jolting pains. These pains, however, are followed by much milder sensitivity and pain that lasts a long period of time, and often shoots pain on each down-step.
