I have been struggling since Feb with fatigue, weakness and general change in fitness. I have had cardiac problems (under control)and was having investigations to see if that was the issue but there doesn't seem to be anything obvious. I had a cardiac mri which showed a lesion on my left breast and I had a consultant appointment and a mammogram which was clear. The question is should I believe that there's no issue or should I have another scan? Im torturing myself as I don't know what was shown on the mri. I am getting zero gp support and I am having to push constantly to try and find out what's wrong. I'm desperate and very low.
