62,Female-Hello, I think I may have a condition (muscle spasm) but I’m not sure. I have chronic pain on the left side of my back that spreads to the left side of my stomach. It’s painful (like needles puncturing),itchy,as well as,burns. What’s interesting is that during the day, the pain isn’t as bad as the night as I tend to try to soak up as much sunlight. The nights,however, are pretty bad. I’ve tried heat/icing the area and massages. What also helps is apple cider vinegar (topical) as it is soothing. But the pain is chronic and U don’t know why. Can you help to diagnose my condition,please?
