Hey, Jim Low! My husband has a similar problem. He also feels sitting bone pain. An IT professional wants to sit in the same position and work long hours without rest. This pain hurt him a lot, especially in the workplace. He tried various medications and treatments but eventually recovered from physiotherapy.
If people like you are confident in trying this, I'm not sure it will work-alike that for everyone. In the case of my husband, it suited him. He still follows some of the exercises prescribed by the physiotherapist.
