Do you ever see a chiropractor? I find that having adjustments every so often really helps with the back and shoulder aches.
Going well! There's one that Im really excited about despite having spent nearly $300 on silicone so far and its not even completed yet LOL.
When my shoulder was really bad, I went to a physical therapist every week and the one thing that finally made a difference was him adjusting one or two vertebrate at the base of my neck. It was strange and seemed like a long shot at the time, but that’s what I think really helped me recover. I haven’t been to a chiropractor in a long time, but I used to get adjusted by someone wife a year. I don’t know why I haven’t recently.
Post some pictures of your new project.
