HI, I have recently (within past 2 weeks) noticed some swelling in my feet and lower legs. I have elevated them at night, but swelling returns next day. It comes off and on. Not severe, but there is a feeling of tightness and I notice a little swelling on top of the feet and very little in lower part of leg. No other symptoms that I know of. I am in general good health. On no heart meds. Can walk 3 miles. Get a little more short of breath than I used to, but I am 70. Weight is 130 and height is 5 6 Is this anything to be concerned about? It is summer and temps are high. I am on my feet a bit, but have time to sit and relax.
