Does anyone else getting swelling in body? Especially in legs? My body feels heavy and I get really dizzi and blurry vision, ringing in my ears etc ! I was giving the all clear in 2016 for rectal cancer , I am 35. I was doing so well and feeling amazing.. now I have these strange symptoms back again?
