Hi lynch. Sorry about your pain.
And sorry about your wait times. Not so great here in the US either with private insurance (and mine is "good"). I've been waiting since January for an appointment this July with a PN specialist.
And smurff, I have very sharp pins and needles in my left thigh from a hysterectomy, so I believe surgeries can cause nerve damage. Even so, I'm thinking that it's less likely if it's both feet, even if you had them both done at the same time. But I'm just guessing. Maybe others have another take.
