Here is a method I use to fix my back.
Put your back against a door jam.
Put your arms straight up then bend your arms at the elbows.
Reach back and grab the molding on each side of the jam behind your head.
Pull your head and neck against the jam tightly.
Now use your legs to push your spine up against the jam.
Start at the neck and slowly roll your spine against the jam until you reach your tailbone.
Hold it in place - exhaling deeply can help you get more pressure.
You can push really hard.
You can usually feel the offending vertebrae move back in place.
A second move that helps is to reach across to the other jam and push hard with your hands.
Do you have any oil or butter? I made some oil and it really helps with pain. I have also been applying it to some precancer/cancer on my face and it is killing it! I am not easily impressed and I think smoking is OK, but these oils and butters are amazing. I can't wait to make some edibles with some kush
Cheers,
Mo
