I don't think smoking helps neuropathy pain but I've never smoked so have no experience. Here's some research on the topic...

"Smoking is a risk factor for neuropathic pain development. In the results of our study, it is seen that the probability of neuropathic pain development increases as smoking duration and addiction level increase. This rate increases even more in the indi- viduals with diabetes diagnosis. Jul 10, 2017"

I sent you a 30 minute response and it got lost when I tried to send it. I send you another note tomorrow.

Have you tried omeprazole for your gerd? Their are prescriptions strength omeprazole.

I have non-length dependent small fiber sensory neuropathy, which means it is from the top of my head to the soles of my feet. Sometimes i’ll have neuropathy that is in my mouth and its almost impossible to eat or brush my teeth. Because of that I have gotten yeast infections ( thrush) in my mouth. It’s hard for me to walk or put pressure on my feet in the mornings and at night.
I also have Automatic Neuropathy. It attacks nerves that you do not control. Like pupil dilation or constriction, your heart……. My top part of my heart is almost dead. I had a pacemaker put in about seven years ago and at that time they gave me five years to live. It is getting to the point where my electrical system in my heart works sporadically. It has gotten so bad there is no longer any treatment for me and I am on hospice. I have been given less than six months to live. This disease has attacked my vision, my heart, bladder and kidneys. I can hardly pee anymore and will soon have
To put a catheter in every 4 hours to pee. Once
you start using the catheter you can’t go back and I will also have to wear depends for leakage. I have been dealing with neuropathy for 15 years now. I fall, I pass out I’m on oxygen full time.
I do not have gerd but I have terrible acid reflex. About five years ago I had some seizures.
My friends who are dying of cancer feel bad for me because they have very little pain and I am always in horrible pain. This disease has to be one of the worst diseases to have. I also get autonomic storms. This is where your electrical system goes haywire and you sweat profusely you get unimaginable pain. You vomit profusely and I usually make 30 trips to the emergency room a year. I haven’t had one since being placed on clonazepam and Valium.
What terrible is my son has it and in some respects his is worse because of none stop seizures. It’s affected the electrical pathways in his brain. He is 37 and was told he will not make it to 40. He also deals with tons of blood clots and they don’t understand why this is happening. He smokes pot non stop to control his seizures. He use to love getting buzzed but now that he has to use marijuana constantly he hate it.
