<s>[INST] 4th lumbare disc on left side extruded; three of four others are either protruding of bulging. I do not want or need surgery. Until a month or so ago, I was making excellent progress w/ pt and moderate exercise, including hill climbing and some running. Not the right lower back, buttock, and right upper leg hip joint ace. There s sciatic nerve tingling in right and left legs, usually from ankles up. What is this? [/INST] Dear Sir/Madam, I thank you for having faith in Chat Doctor and for seeking help on your issue; I have gone through your symptoms, and in my opinion, as you have written your findings probably from an MRI, the fact remains that conservative treatment remains the mainstay only if you have no neurological weakness or numbness, and if you are responding to it. If your symptoms are getting worst, then surgery is the only option, yes the method of removal depends on many factors, microscopic removal, endoscopic removal or open removal all are options. don't make up your mind that you don't want to go for surgery, as once the nerves are damaged beyond repair no surgery can then be of help. I hope I have been able to provide you with a satisfactory solution, if you want to clear any doubts about my opinion, feel free to contact. Special note-Any medication prescribed needs to be taken after consultation with your personal doctor only. Thanks </s>
