I had a colonoscopy last week, they couldn't reach all the areas, so I was sent to a lab where they did a procedure with an inserted balloon and then xrayed the area. I went home after this was finished. Also, during this time, I've started taking a new medication called symthroid............... Today and this evening my legs are beginning to well pretty badly, not sure whether either of the afore mentioned conditions can be involved. Plan to take care of it Monday with my family doctor but wonder if, in the meantime, can I relieve this swelling?
