I'm a huge advocate of natural healing and can praise numerous methods that have helped me over the years. Majority of my pain and stiffness lie in my lower back. I have scoliosis, which unfortunately is only corrected by surgery (which i'm not willing to do at this point). However, to keep the pain at bay without using medication, I use either a cold compress or a wrap called the BFST. After i do any exercises that cause a tweak in my back, I put a cold compress on it. Cold is by far the number one best natural remedy for pain! On days where I am not active (no chance of inflammation) and my lower back gets stiff and sore from tight muscles/ligaments etc., i use the BFST (blood flow stimulation therapy). This is a natural way to stimulate more blood flow to the targeted area. In most cases it will help heal any soft tissue damage (via the nutrients and oxygen the blood carries). It has done wonders for me and allows me to be med free :) I've attached the info from what i use.
