Hello and thanks for posting the query
You are following a right schedule to get cure from the pain. The only change that can help you is do hot fermentation instead of Ice fermentation. Do not wear weight till the pain subsides. If your pain does not subsided in 2-3 days than you have to do your X-ray lumber spine done to rule out any fracture
. Use hard bed to sleep and for slight movements wear lumber belt to stabilize the spine.
Hope this will help you.
