I was told for years I suffer from costochrondritis. I just feel like I received the wrong diagnosis. My chest near my heart hurt so bad, I clinch it tight and struggle for air, every breath feels like my last, I can hear a popping sound if I take to much of a deep breath so I slowly breath like a fish outta water. My back sometimes hurt and I would do nothing strenuous. If I take normal steps I feel like im dying, so I glide to wherever I need to be. Ive read that costochrondritis can lasts up to 8 weeks, but, this last for a day or two, then comes back a month later. So my question is..Am I having mini heartataches, costochrondritis or is it leukemia (ALL)?
