SUNSHINE HELP!!! I'm 19 and I'm having the SAME symptoms, trouble breathing through nose, pebbly stools (even tiny tiny drips of blood on toilet tissue), I'm also cramping in the abdominal area a little bit, fatigue/lightheadedness very fast after movement or any physical activity, etc. anyways the weirdest part is when I typed in these symptoms and clicked on your forum.. I realized u had been taking amoxicillin and prednisone.. I have been taking those exact two, and only those two medicines, JUST prior to this occurring... Although I haven't found worms or anything in my stool (And I have been to ER, no heart, serious breathing problems etc) I'm guessing I have a similar issue to you.. I'm praying that my doctors appointment and colonoscopy on the next few week comes back good, but if they do, Idk what I have or what to do. It's been a while since ur post, can u updAte me on ur progress and anything you have learned ?
