Hi.
I myself struggle from the same problem. Sometimes the pain is so severe that I get anxiety. The worst part is when the pain sets in my head and gives me enormously headaches and migraines. Where does your pain appear? I also have a lot of pain in the left side of my stomach, underneath the ribs and my left knee and arm. The left side of my body tends to be very weak. The reason why I wanted to reply was to ask if you know why the pain appears? I have found out in the later years that my pain is actually chronic mercury poisoning (from vaccine and amalgam fillings). Many people I know suffers from pain due to toxins in the body, especially mercury. Fluoride also can give very stiff and painful joints. And these toxins give a lot of symptoms/illness in the body (including anxiety, depression, foggy thinking, pain, Fibromyalgia, ME and other serious diseases)
I also do not want to take medication, but I have to on the worst days. I try to walk/move/stretch as much as I can, though it is very hard, because the pain often paralyzes me. I also try to get enough rest and sleep and meditate. I know that pain is caused when the brain picks up “error signals” from the central nervous system (“something is wrong here!”, it shouts to the brain). I also try to self heal my body, by sending “light into the dark areas”. I really wish you all the best and hope that everything will work out to the best for you.
