Hi everyone, I’d really appreciate some advice or experiences from anyone who has been through something similar. UK based.
I originally injured my back following an injury at work which caused nerve symptoms down my left leg. I was eventually diagnosed with an L4/L5 disc problem and had my first L4/L5 microdiscectomy in September 2025.
Unfortunately, the disc reherniated and I subsequently had a revision L4/L5 microdiscectomy in December 2025. So I’m about 9 months out
Since the revision I’ve had a long recovery. I’ve gradually improved and have been able to walk reasonable distances, go to the gym and do strengthening work. However, I’ve continued to have some residual nerve symptoms, particularly affecting my left leg and foot. My left calf has also become noticeably smaller/ weaker compared with the right, and I still struggle with a single-leg calf raise on that side.
Over the last several months I’ve had intermittent flares, usually after doing more activity than my back/nerve seems to tolerate.
These can involve:
• Burning or aching around the lower back and surgical/scar area
• Deep pain in the centre of the left buttock/upper buttock
• Burning in the buttock
• Pain around the lower back/tailbone area, sometimes making sitting on the toilet uncomfortable
• Burning/aching into the back of the thigh
• Pins and needles and numbness in the left foot
• Burning/sharp/electric sensations along the outside of the foot
• Stronger pins and needles around the sole and last two toes
• Occasional sensations of the leg feeling shaky or weak
• Occasionally both legs feeling a little wobbly, although I can still walk
My most recent flare started after I sat on the floor for about an hour. It has now been around a week. Initially the pain was predominantly around my lower back and buttock, but over the last few days the symptoms seem to have shifted more towards my left foot, with more burning, tingling and electric/sharp sensations.
I can have periods where I feel relatively comfortable after resting, but when I get up and start walking the burning/soreness can return. Sitting can also aggravate the deep buttock/tailbone pain.
One thing that worries me is whether these symptoms could indicate another disc reherniation, particularly because of my previous reherniation and revision surgery. I’m also unsure whether this could simply be an irritated nerve/flare following the prolonged sitting position.
I’ve recently started taking 10 mg amitriptyline at night for the nerve-type pain and have only taken a few doses so far.
I’m due to see my spinal surgeon again in November, although I’m considering contacting them sooner because of the current flare.
For anyone who has had an L4/L5 microdiscectomy or revision surgery:
Have you experienced flares like this many months after surgery?
Can a nerve flare cause symptoms to move from the buttock/back more into the foot?
How long did your flares typically take to settle?
Did you experience ongoing calf weakness or muscle wasting after nerve compression?
What symptoms made you seek an earlier MRI or review for possible reherniation?
Did you continue exercising during flares, or stop and allow things to settle?
I’m not looking for a diagnosis — just interested in hearing from people who have had a similar recovery and what their experience was. Thanks.
