Suggest Treatment For Pain In Leg
Nerve block seems like the logical next step.
Detailed Answer:
I read your question carefully and I understand your concern.
Chronic pain is often very difficult to treat and it is also affected also by concomitant conditions like depression which you seem to be suffering for the moment.
From the list of options I see that you have already gone through the usual first ones like Acetaminophen (Tylenol), nonsteroidal antiinflammatory drugs (Aleve), botox injections, drugs for neuropathic pain like Gabapentin. From the medication options it could be tried switching from Gabapentin to Pregabalin which in a small percentage of patients provides better relief. Also if the pain is well localized, application of local anesthetics like capsaicin cream could be tried.
Otherwise the remaining option is nerve block. It is a widespread procedure and in good hands it has a very low rate of complications with good results. So I believe that you should have it.
I remain at your disposal if you have other questions.
