Disc bulge and severe sciatica at age 25

I have a really severe pain shooting up from my left lower back to the toes of my left leg. I also have some numbness and a little less movement in the toes of my left foot when compared to my right; I've had lower back pain for almost the past two years but this condition only occurred a week ago. My MRI report says: Disc desiccation with postero and left para central disc protrusion at L4L5 level compressing upon thecal sac and abutting left sided nerve root (Thecal sac diameter: 08.00mm at L4 L5) I wasn't even able to move for a few days and needed assistance even for going to the washroom but now the pain has decreased by a bit and I'm able to walk a little myself without assistance, but the pain is still there in my ankle and hip along with the numbness. I don't want to opt for surgery and I want to get better without it can someone please help me with a piece of advice so that I can recover as much and as quickly as I can? Thank you
