Hey guys, the last few months, I am constantly getting upper back pain, like the middle of my spine, very painful. It’s there all the time. I feel the cause could be from when I’m looking up cleaning top windows or when my pole is at full reach or just the strain I put on my back from when I’m moving the pole at high reach. Does anyone have same issue or had, and has a solution? I really like my job but this constant back pain turns me off this work as I’m in constant pain every day with it.
