100% certain that it was the cause of my shortness of breath. After 9 1/2 years of dozens of tests… my husband thought of it. Before it happened I had been working out at the gym weightlifting and since I was 60, perhaps more prone to this happening? But we never put two and two together… we thought one of the doctors would 🙂 my husband was the one suggesting the X-ray of my spine awhich led us to a neurologist. In addition to having shortness of breath, I had what we thought was angina or chest pain in the left side and went down my left arm and my thumb and through the years my thumb got worse and then I became off-balance and that was the key I guess? The nearest surgeon performed an anterior cervical disckectomy with fusion at C5/6, which relived all of the above symptoms. I went from walking up two steps and stopping to breath to doing 26 flights yesterday ( were moving from level to steps now that I’m healed 11/2 years out and 74) good luck … let me/us know.
