I’ve been having a lot of pain on the left side of my pubic bone and it’s gotten where it’s hurts more than just being a annoyance. It hurts a lot when I stand or walk too long. Does belly bands help with this? If so which ones are best for it? I looked it up on google but didn’t have any luck at all.
