I have started experiencing pressure in my chest like a heavy weight is on it, but it doesn't last more than 15 minutes at a time. My doctor sent me to cardiologist who did 2 tests and both came out fine. But a few days ago I was washing my hair in the shower and had to hold on to the soap dish to steady myself and try to catch my breath. My arms were aching terribly and it hurt to keep trying to wash my hair. I got dizzy, light-headed, and felt like I couldn't get enough air when breathing in, which became labored. I rinsed my hair, grabbed a towel and climbed out of tub and sat down to catch my breath. I was really scared as this has never been this severe. I went and laid down until my breathing was restored and I was no longer struggling or dizzy. I made an appointment with my doctor for Monday. A couple of hours later, my vision became impaired. WIth and without my glasses on, I was seeing a circle in each eye of distortion as if the light waves were bent. That lasted about an hour. In the next hours my hands and left arm got stuck in a Charlie horse that was painful as I couldn't move my fingers back into being straight and relaxed. I know I need to exercise and eat more vegetables and fruit as I always was a healthy eater prior to the last year. Sometimes I forget to eat, so am now keeping a log of daily meals to ensure I get well rounded nutrition. My biggest concern is the pain that is now coming and going is under my left rib. Since I had spit up bloody mucous twice in the last maybe 6 months, my doctor had my lungs exrayed, and nothing showed up. He did say if it happened again he would order an MRI or some other test that would show what might be causing this. I do not smoke, but did off and on (mostly off because of breathing difficulties, I have COPD). I am concerned about cancer or some other lung disease developing. Please give me your thoughts. As I said, I will see my doctor Monday afternoon. Thank you.
