Perhaps you may? About September, a traumatic experience in my life, caused me what felt like a broken heart. So, a month into my trauma, what I felt happen was body overload. I could feel all the muscles in my upper chest area (decolletage) region, felt like around my heart began to tighten up, I could feel every muscle twisting inside my chest, I though I was a having a heart attack. This happened for over a two week period, and this is after being in a Psych ward for a week . I chalked it up to stress related due to the events in my life in September. Yes, I am a smoker. I have been for 35 years plus. Yes my lungs are weak and in September the nurse stated if I kept smoking I would be on Oxygen in about two years, and showed me how my lungs are longer than average, due to years of abuse. The tightness does not feel like my lungs. My upper chest area felt bruised and if I pull my shoulders back it is tight, not normal. I now have had laryngitis for about a month and was prescribed Amoxicillin took last one today and just a bit better, but it's been a month. Hope you have enough info to give me a diagnosis.
