Tingling & numbness. Mine started in my right arm immediately after receiving a pneumonia vax back in 2012. Immediate diagnosis by a neurologist was damage from the vax.
Within the year, whilst trying to chase this up, the neurologist withdrew his diagnosis. Closing ranks! GP disinterested.
Has gradually spread throughout my body until today it affects my legs and feet. Wild, guessed-at diagnoses have included - Arthritis, Diabetes, Stenosis, Cervical & Lumbar compression, Myelomalacia from some past trauma (I am unaware of). If it were that, I should be long dead.
The latest from my Podiatrist is Ischemia. I'm researching that now.
Just to give you a few things to research.
I wish you all the very best.
