My foot that was damaged by MS swells mostly in the evenings. Since only one foot was swelling it did concerned me.
I went to a vascular surgeon. He did a scan of my veins and fortunately they were clear.
The doctor said neurological damage from strokes, MS etc. can cause the feet to swell.
He said I could try compression socks. However they would be too hot for me.....the heat causes my legs to cramp. At least elevating it does help.
Oh my! the aging body....have you ever heard of such?
