Hi ! I have never tried Doluxetine, but was on Gabapentine. Gabapentine didn't work for me, but if you are not getting relief from Doluxetine, Gabapentine is worth trying.
Tylenol Arthritis is worth trying. Personally, I love it. It kills arthritis pain and the wierd thing is that I also get relief from my shoulder and neck pain. I also take Cyclobenzine 15 mg with the Tylenol. It works for me. If you take it at bedtime, it helps me to sleep.
Low dose marijuana gummies are also worth a try. It really works, but I stopped because I was constantly hungry and didn't like the way it made feel.
Good Luck ! If you dont mind replying, I am interested when you find what works for you!
