@johnbishop Thanks Colleen and John! A little update about my condition since the last time I had posted in April. I think I was misdiagnosed with Costochondritis and it turned out it is nerve pain in the chest. The more I used my CPAP machine the worse it got. So I stopped using it. Also, what made it worse is that one day I was doing Costo stretches for the first time and the next day I developed unbearable burning nerve pain from my right chest and radiated all the way to my whole back (mostly my upper and mid back) and left chest as well. This was after I stopped using my CPAP by few days. I have done MRI for my Cervical and Thoracic spine and brain but everything was normal (no discs, tumours, or MS, etc). My family doctor is not sure what is causing it so he referred me to a neurologist and I'm waiting to get an appointment with him. I'm not sure if the shortness of breath that I have mentioned before is related to the nerve issue or Sleep Apnea but I have migraines as well and the shortness of breath always comes with it. I have read research papers online that Sleep Apnea can cause peripheral nerve damage and migraines due to low Oxygen levels in the body. But I'm not sure about the shortness of breath. I also don't know why the pain got worse with using the CPAP machine.
