My back (kidneys) used to debilitate me at times. Triggers for increase in the pain were eating or drinking anything with high sugar ie pop. Taking a hot bath ; ) or using the heated seats in the vehicle in the winter time….all three of these would cause instant lower back/kidney pain. Relief came from swimming in an ice cold lake lol but i don’t recommend it…I think yeast likes warmth and hates cold..
One day at a time. There are a lot of great options for treatment out there. Hang in there…always here to help in anyway I can.
