I'm 28 years old male from Dubai. I've been suffering from chronic low back pain for the past 4 years. I have been managing it with pain killers and some exercise. A MRI last year showed a slight bulge at the L5-S1 level but the doctors said it wasn't serious. A week ago, I woke up with severe low back pain radiating to my left leg. I was taken to hospital where I took some strong pain killers for the pain and went for a new MRI. The pain was gone but my left leg has become numb and weak. The Achilles reflex is absent and I can't really move my toes upwards to overcome the pressure the doctor applies by his fingers. The new MRI showed an obvious disc prolapse and immigration at the L5-S1 level. The doctors suggested immediate microdisectomy. They scared me when they said that I will never regain the strength of my left foot again and that if I didn't go for the surgery right away, my leg will turn into a drop limb. I'm taking a second opinion on the MRI from other specialists and arranging for the surgery in my home country. I'd really appreciate it if you give me some hints on the proper postures for sitting, sleeping and walking. Any precautions I should take during the coming week before the surgery.
N.B. I will have to go on a 4hrs flight to my home country for the surgery, is there any risk?
