I m 57 years old.always active. Woke up about a month ago with pain.My left arm and neck hurt,like I slept wrong. I don t sleep on my left side..I have a knot on top of my left shoulder, a good size. I ve tried different things.nothing is working. Last two days the pain is worse,a and I have numbness in my fingertips.I ve always had scrapes and bruses.Nothing like this.I do have my doctor..Your insight would be greatly appreciated. Thank you.
