Hi, I have swelling issues of the right side only, hand and feet. I only have pain in my leg, it feels like it becomes really hard and my toes get num. I have no pain in my hand. I also have difficulty urinating sometimes. I can't seam to associate the symptoms to anything in particular. It comes and go. I'm ~5'7", 160lbs and I'm trying to loose weight by exercising and eating well, but It's not helping. My doctor wants to do blood analysis but It doesn't work, I have the flyth syndrome, I'm so scare that I almost faint, the Dr trys to pull blood but nothing comes out. Any idea of what I may have?

Thanks
