After paracentral disc protrusion at l5 s1 level inmri after three weeks rest/medication pain is almost negligible what is best treatment going forwad?

Do your lumbar: strengthening exercises to increase your paraspinal muscle tone and durability, which in the long term will help strengthen your back against trauma and/or recurrence of symptoms. Physical therapy is always a good answer for vertebral problems. I would make sure I do my back exercises everyday for at least 15-20 mins, and avoid situations where you may have to strain your L5-S1 disc.
