well i am back.....the doctor looked me over again... he said since the pain is going from my butt to my toes.. it is for sure my nerves in my back, he is afraid that i have a disc out of place and that it is pressing on a nerve. he wants me to do some exercises at home as well as phsyical therapy 3 times a week for the next three weeks.. then come back to see him.. if the PT does not help by then, then we will do a mri and steroid injections.... i am scared of the mri/ cat scan mahcines..... i hate needles..... so please help me out and have good thoughts that the PT will help me so i dont have to have an mri or any injections......
