I am 17, female, I was born with bilateral pars defect and have spondylolysis in L5 to S1 area that has progressed to a 10% shift. I take Dolased once every couple weeks but the pain in my back is getting worse. I get burning pain like Red Hot pokers are being wedge in my back. I get a numb sensation across my shoulders typically on my left. I go numb in my butt down the back of my legs. I can’t sit or stand for more than an hour an a half. I need to know if I can fix this or help with the pain
