Brief Answer:
Imaging necessary, medication for chronic neuropathic pain.

Detailed Answer:
I read your question as well as some of your past questions carefully and I am really sorry about the disabling pain you seem to bee in.

It might have been useful if you could have uploaded some medical reports, in order for us to better understand the type of surgery you've had, the anatomical structures involved, the complications which happened and what tests were done. You speak of a hematoma, but if surgery was 6 months before whatever local hematoma there was should be long absorbed by now, so shouldn't cause any new symptoms. Also while a surgery of that kind may damage peripheral nerves, it shouldn't affect spinal cord or the nerve bundle inside the vertebral column, so there shouldn't be any pain going up the spine. Either there is some new non related lesion, or it may be an irradiation of the chronic local pain (which disabling and excruciating as it may be is not threatening of any permanent damage if that is what you mean by a matter of concern).

So I think if there is a new type of pain, involving the spine and spreading in the limb, diagnostic imaging, preferably with MRI is necessary to exclude new lesions.
If on the other hand it doesn't show something new (that doesn't mean that there isn't residual nerve damage causing pain, only that there isn't any new process which might required surgery) then it is a matter of pain therapy, preferably by a pain specialist as yours is not an easy case. Medication for chronic pain should be started. I see in one of your previous queries amitriptyline has been recommended....it is a valid alternative with which I agree. Other alternatives for chronic and neuropathic pain which might be considered would be duloxetine, gabapentin or duloxetin.

I remain at your disposal for other questions.
