Hello,
I have studied your case.
For

I will advise you to do MRI spine
For these symptoms
analgesic and neurotropic medication can be started.
Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help.
Physiotherapy like
ultrasound and interferential therapy will give quick relief.
I will advise to check your vit B12 and vit D3 level.
My patients get good relief with holistic approach like pranayama,
yoga,. You can also start them.
