Thanks I think it's to do with brittle bone disease or DVT as I suffer with these I also have diabetes & inflammation I've had problems with before, my legs feet ,& ankles swell through. Water retention , I think I should phone my GP or NHS to get advice cause it could be something that needs sorting asap, or it may be nothing to worry about, right now I'm worried cause of pulmonary embolism in my legs cause I've had cramp too.
