My feet and legs are swelled to the point of bare being to walk . inwas there from 1:00 am till 7:00 am .im that time all they did was blood work and gave me injections of laysics my breathing issues were not addressed before I was discharged . when being discharged I was given a oxygen tank and was told to walk out the side door . inwas not given discharge orders and my IV was left in for me to have to take out myself when I got home while still having issues breathing
