Brief Answer:
not sure where the quesiton is....

Detailed Answer:
of course I cannot say much about your particular situation... ah, I see from your previous hsitory... neuropathic pain from chemotherapy.
There are a lot of medicaitons in addition to narcotics that can be helpful:
amitryptiline
lidocaine as patches
gabapentin.
Then more serious treatments would incude nerve ablation with chemicals (capsaicin) or surgical.
Tens units might also be helpful
60 mg oxycodone .. I suspect multiple times a day... is a high dose.

Brief Answer:
very individualized situation

Detailed Answer:
basically cutting the nerves.
http://www.ncbi.nlm.nih.gov/pubmed/0000
can't say it better than the article.
Depends upon where specifically the nerves are that are connected to the pain. FURTHERMORE, there is certainly no guarantee this is going to work especially since cut nerves often produce neuropathic pain (but generally a neuropathic pain that your meds would treat well in over 2/3's of patients with cut or traumatically injured nerves). Spinal stimulators and this article.....
http://www.ncbi.nlm.nih.gov/pubmed/0000
came up while searching for surgical options.
Most of the surgical options would not apply and none of them would apply if the pain is very widespread. BUT interrupting the pain pathway anywhere along its route. Spinal dorsal root ganglia surgery, spinal stimulators are some options. Cutting nerves out, putting poisons onto them are others.

Since this involves plain damage, not many surgeons like to do these surgeries and you'd have to call all the surgeons in the area starting with university hospitals to find one.

In the meantime. XXXXXXX XXXXXXX or mentholatum oinment are possible and are a bit cheaper than 300 grand (more like 10 bucks total). Careful about local skin abrasion.
