Im currently taking nortriptyline for migraine headache. i just started experiencing tingling in both feet. is this dangerous or normal?

Go to drugs.com and look up all side effects noted for your particular med. Normal would be if it occurred in 95% folks like you.

It may or may not be a side effect, and the best way to objectify is to put the nortryptyline on hold for several weeks. Years ago, I used this agent for migraine prevention, but now in 2023, there are numerous far better prophylactic approaches, both OTC and prescription. Nortryptyline would not be my choice these days! Get a second opinion.
