My legs and feet swell every year from left to right for the last 10 yrs. I think it maybe the ice tea or the sugar I drink every summer. The other Doctors call it celluitus, or a form of gout . I also think it maybe related to the chemical I was exposed to when I was working. I worked on a machine that put a coating on the paper to make it printable. I use to ware support sox but my leg would swell to cut off circulation. then i would have to stay in bed with my feet proped up for about a month or two taking antibiotics and pain pill , and some time fluid pills. Sence i stop working when it start I can put my feet up more often so it don t last as long. Maybe a good month to 6 weeks.
