Hi Roshan,
Sounds rough and I hope I can help. Im sorry to hear you are having the pain of coming off of Lyrica as well as healing pains 
That drug is good one for nerve pain.
Last time I tried coming off, I was very emotional and could hardly walk From the nerves firing off constantly .
I will be hoping the best for you, please take it slow. Slower than slow if you can. Please look at topicals if you haven’t already. It’s not cheap, but Hawaiian noni cream is cold if you have nerve pain and don’t mind cold.
it is good for deep pain. Cryoderm roll on lotion. Cannibis salve. List goes on. Ice Packs.
Stuff I use anyways.
I wish you were on something else that would cover your pain enough so that it would ease the difficulty of tapering. As most of the docs I have met, only hand the drugs out and do not know what we endure at home tapering. Mentally, emotionally, physically, socially etc.
Amytriptaline …I just felt sleepy and this med Helps increase hunger and I gained weight.
So I have was take the sister drug called Noritryptaline. I like this one for myself for mood booster, pain and energy. Also, I can play with the amount and it is easy to come off of if I so choose. But that’s me. Everyone is different.
Im also on a baby patch called butrans (buprenorphine) delivers small amount of med during the day. Since I have Such large pain and it Will breakthrough during the day. the other meds come into play.
I always look at the coming off part too.
Other Meds that help me.
*Flexiril
My neuro just gave me a migraine med
*raz-Triptan. (Migraine med)
It is working very well. Only been using for a week though.
All other meds I have had experience for 6 years.
Have you tried
*Nabilone? (cesemat) nerve pain?
Nabilone is a very good med for nerve pain. It is my go to when I was trying to come off of Lyrica. That and *tramadol.
That is my experience. Hope that you are able to go slow and can find some energy to take an Epson salt bath. They really help the aches.
They are a lot of work when in pain, but at the start of a day, it can help the nerves big time.
If I can answer any questions? I been thru lots of meds and pain so idk
Take care and bless you
