No doctors seem to know what this is... anyone find that strange? I think these things probably make you sick. I recently thought I was getting a cold, sore throat, congestion, and the same day I coughed up a big (the size of a large pea) chunk. So I found this site, and cleared my right side out and within hours did not feel sick...... I think the doc doesnt know what these are cause you get sick from them sometimes and come to see him so he gets paid. Going out of country to get top notch medical treatment $10000 having your health priceless.
