I have studied your case.
You may need to do MRI spine again to see for nerve compression
If your new MRI shows disc bulge with nerve compression then surgery may help.
Due to compression of this nerve root
there is tingling numbness
in your leg and pain associated with it.
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.
Yes peripheral nerve
stimulation may help.
I will advise to check your vit B12 and vit D3 level.
