i fell again last week my oxygen level was 76 for a while. after i fell my ribs have been sore as anything ans every day in the morning my mucus had blood in it. i didn't do anything about it, and my mucus has been clear but my ribs still hurt, i'll give them another week before i see my P.C. because this has happened before and it takes about 2 weeks to start to feel better. it seems every time i look up something falls out of the sky and lands on me!
