I lost consciousness last night after having severe difficulty breathing after exercising. I attempted to use an inhaler twice but it didn't help. My chest became very tight and I felt unable to expand my lungs, then I couldn't hear and saw black dots and my skin felt strange all over. I leaned against my husband for support and lost consciousness. He said my lips turned blue and I went boneless to the floor, then got rigid acting like I was clawing for air. I came to a few minutes later
