I've been in so much pain. I thought the pain was due to damaged nerves in my foot
What was the real reason for your pain?
My walking stick was much shorter than a normal walking stick.
I'm glad you found the real reason, but pain in the foot is still scary especially since you're using a stick. It's better to be safe than sorry and get your pain inspected. It could be something much more serious.
I find it hard to trust doctors.
Why don't you trust doctors? Doctors are there to help you get better. They won't hurt you on purpose.
