Chronic Knee Pain (Right Knee)

It has now been a few weeks since my last update.

I've now received a diagnosis--peripheral neuropathy--and I've begun treatment for the chromic pain I'm experiencing. I'm now taking the following pills to hopefully combat this problem: Gabapentin Actavis (300/600mg), Noritren (30mg), Tradolan Retard (200mg), Arcoxia (90/120mg). I've also been treated with a Qutenza patch in the hospital a few days ago.

I'm currently still in a lot of pain, but have noticed a little bit of improvement in the hypersensitivity of my skin around the calf and knee. My skin is still painful to the touch, but perhaps 10-20% better than it was before.

To be quite honest, I'm totally exhausted by taking all the pills and the pain and I'm having trouble living a normal life. Quite worryingly, I'm now noticing pains in my right ankle as well and think that the area effected is getting bigger.

Does anyone out there have any similar experiences or words of advice? I could really do with some support from people with similar problems.

Also, I've been looking into other pain treatments that do not have so much of a negative impact on one's concentration and memory. My colleague has suggested that I look into Sativex a cannaboid drug which may have benefits for neuropathic pain. Does anyone have specific knowledge of cannaboid drugs and their benefits vis-a-vis limitations?

Thank you to anyone who can offer helpful information or a supportive word or two.
