Painful back knots
I'm a 54 yr old woman. I've had back problems for years. Without going into all the different things I've tried, chiro, massage etc. I wanted to see if anyone had any idea as to why I get hard painful knots all over my back by doing pretty simple things. For the last two days I've been removing old wallpaper, it's not particularly strainuous, there is some repeticious movement and reaching. Especially while reaching, it is extremely painful at the muscles going from my shoulders to my neck. They get rock hard and feel like a hot knife is going into them. Today I feel like a truck hit me, I can't hardly get off the couch. I am a very active hands on kind of person and love hard work, and this really affecting being able to get things done. I'm not overweight and take good care of myself.
Does anyone have any suggestions on what I should be doing to maybe make this better? Thank you.
