I went to my doc about swelling in my arms and legs. They put me on to water tablets and I don't understand this as I already wet myself all the time and get large pads from the continence clinic as it is really bad. The swelling did not go away either. I had radiotherapy really two years ago in my eye for militant melanoma of the iris. I am wondering if the swelling has anything to do with that or is it just my fibromialgia playing up. Arms and legs are in so much pain. Fed up with all of it.
