Welcome @willec49, Neuropathy certainly has a lot of causes and the conditions could be related but I'm not sure anyone here can answer that question. You mentioned you have an EMG scheduled for Wednesday. It might be a question you can ask your doctor at a followup to the EMG when you get the results back. You mentioned being on medications. There are some medications that can induce peripheral neuropathy. The Foundation for Peripheral Neuropathy has a list here - https://www.foundationforpn.org/causes/other-drugs/ if you want to check and see if any you are taking are on the list.

Since you mentioned spinal stenosis, here is some information that may be relevant -- Spinal stenosis. A common cause of podiatric symptoms: https://pubmed.ncbi.nlm.nih.gov/9086718/
Do you think the new symptoms might be related to your spinal stenosis?
