Okay I am ready and I am posting my answer here.
Okay I see that lyrica was helping you with pain but unfortunately causing weight gain so had to come off it. What I will do is provide you with a list of varieties of treatments that are available to help with your neuropathy symptoms like pain & numbness etc.
This following is the list of several options to treat the neuropathy symptoms you are having;
1) Nervex (a neuropathy pain relief cream)
2) Capsaicin skin cream (another neuropathy pain relief cream)
3) Evening Primrose oil (a herbal preparation)
4) Neuroveen (a homeopathic treatment)
5) Lidocaine anesthetic pain relieving skin patches
6) Low Level Laser Therapy (Cold laser therapy)
7) Using medical devices like TENS (Transcutaneous Electrical Nerve Stimulation) or Calmare Scrambler Pain therapy
8) Complementary and Alternative medicine treatments like Acupuncture etc
I am not telling all these above treatments are required in your case, I am just providing you with a list of different treatment options that are available for the control of neuropathic symptoms you are having. And I have not mentioned any treatment that can cause any weight gain.
Along with one or more of the above treatments you may also try nutritional supplements like Metanx (a special combination of active vitamin b12, folate & vitamin b6), ALA (Alpha Lipoic Acid) & Acetyl Carnitine etc and these supplements may help in nerve repair & nerve regeneration and this can additionally help in the relief from the pain & the numbness. And I see that with great effort from your side the diabetes control/HbA1c is improving, but it is still bit high around 7, you may discuss with your diabetes specialist to see whether they can help you further because if diabetes is brought under firm control then that itself can enormously help in the resolution of diabetic neuropathy symptoms.
Please let me know if you have any further questions; and if you feel you have received the answer to your question please rate me so that I can receive credit for the time and effort put by me in answering your question.
