I used glutamine powder 3 times a day for 3 or 4 days after each chemo treatment (taxol). I barely had any neuropathy in my hands and feet but did have pain in the hips and knees. Acupuncture was the answer for those myalgias, neuralgias, and arthralgias….on doxil/carbo, no issues.

I have the chemo neuropathy. I totally understand the shards of glass feeling. I describe it like having a foot go numb then walking on sharp gravel at the same time. In the beginning I used Gold Bond Lidocaine cream on my feet so that I could at least sleep. I also take Tylenol and a THC gummy before bed. My chemotherapy ended at the end of December. Now we're close to the end of April and I do feel some improvement in my feet. (I have the neuropathy in my fingers too.) I don't use the Lidocaine anymore. If my hands and feet get cold the pain gets worse. I have an electric blanket on my bed to help with that.
I've heard and read that it could take a full year for the very last of this feeling to go away.
I had chemo mouth for 3 months and could barely eat. Had that continued, I would have starved to death. Luckily I could tolerate Ensure. But I still lost a lot of weight. I can almost eat spicy food again. Some foods still don't quite agree with me yet, flavor and texture are off.
I hope my information helps.

Get your doctor to give you a prescription for the lidocaine. It really helped me. The patches never worked for me as I couldn't get them to stay on - talking OTC patches for pain.

I took L-glutamine during chemo stopped day before chemo resumed two days after an no neuropathy!

I take 600 mg alpha lipoic acid daily. It is OTC. I do use lidocaine/prilocaine from a tube that my ONC prescribed. He gave it to me to put on port before chemo access to help with the discomfort. It worked wonders for my neuropathy as well. I was also told to take Claritin daily for neuropathy and it really made a difference. I also was given an RX for diclofenac by my PCP. I use all of the above for relief as I have the same feelings as you do. This works for me. God bless!
