Have slight edema in both legs - goes away after few hours sleep at night but by mid day feet and large portion legs swell - seen worst. Wondering if hemmoroids (sp?) bring this on? Sleep at night has been poor for 4-5 days, once day noticed left eye twitch for week or so, possibly dehydrated. Started lasik today. On oxygenator machine due copd dx. 90 plus degrees here - under lot stress 59 yrs old female. thanx
