Ok Baba, we are now in the same boat. My whole Nervous System is Hypersensitive, and I get the Allodynia and other problems as above and in my Bio. I know it's not an immediately practical solution to your current pain, but look into Lidocaine infusions. I also take oral Ketamine which is an anaesthetic that increases the effectiveness of Opiates..
You clearly need something prescribed by your Neuro or PM Team to resolve this. Until then you must avoid slipping into Depression caused by the pain. Have you tried meditation to increase positive thought?
If you can think of any way I can help, let me know.

Dave.
