With your activity level and pain, you should not be comparing yourself to anyone. Your recovery is yours alone. It is important that you manage the pain you have. If that means you take the meds you're on now, then that's what needs to be right now. Please don't start trying to cut back. You're going to hurt if you do.
Those zingers you feel are really common and it most likely is the nerves working on healing. As long as it's just a now and then thing, it's nothing to worry about. It's also normal to need to shift positions when sleeping. You may have that problem for months. It's why we recommend taking something for nighttime pain and using ice through the night.
