pulmonary embolism
"I've been on Xeralto now for a month now and I'm sure it's working quickly, as I noticed within 24 hours of my incident ( small PE in left lung.)   I couldn't believe the sharp pains subsided and breathing improved in that short amount of time.  Since I've been taking this for a month now and actually lowered dose from 30mgs. to 20mgs. daily, I feel worse and worse.  I feel like I have the hangover of the century, all the time, no alcohol, cannot tolerate it on this drug.  Burning eyes, constant headache, extreme headach and fatigue, exhausted, in bed by 6:00 PM usually.  I have two teenagers and a job, finding it hard to carry on with my life.  I'm so depressed.  It's bad enough to have this happen but this Xeralto is making me miserable!"
