Fasting promotes growth of Clostridium sporogenes which elevates levels of indole-3-propionic acid (IPA). In mouse model, improves “promotes neutrophil infiltration into the dorsal root ganglia (DRG), which enhances the regeneration of sciatic nerve fibers”.
Nerve growth is contingent on a type of neurophils (and also a type of macrophages). Arthritis Pills/NSAIDs would interfere with that.
I sustained injury to the back skin nerves (cluneal) and I stayed off NSAID for 6 weeks to allow nerves to regrow. Tramadol would be a good option in meantime.
I tried some fasting but can’t say if helped.
