25 years ago, I was diagnosed with Disc degenerative disease after having serious lower back pain. This was resolved using conventional treatment (no surgery) and for many years, I was pain and symptom free. 3 years ago, I had severe sciatica on my left side and underwent a microdiscectomy at L5/S1. this immediately alleviated all my symptoms and for the next 2.5 years, I had no problems at all.
About 3 months ago, I started with Lower back pain again, and slight numbness and weakness in my right leg and foot, all of which I managed with pain killers and anti-inflammatories . 6 weeks ago I was at the gym, and again experienced severe sciatica, except this time down my right leg. The sciatic pain was reduced by the painkillers and 3 days later, was almost gone. However, The severe numbness in my calf and foot, and the weakness in my right leg has remained. I have had a MRI, showing L4/L5 disk herniation and have been to a neurosurgeon, who has advocated surgery again.
My question here, is whether it is normal for the sciatic pain to go away, leaving the numbness and weakness in the leg, and I suppose whether this will be alleviated by the surgery.
Any help or comments would be appreciated.
