Fluid retention in torso area
I just wanted to see if anyone could provide any information on this strange problem my husband seems to be having. Yesterday, he had a bad headache and his blood pressure was elevated (avg160/105). I tried to help him relax, and he took medication for the BP. I was giving him a back massage to help him relax and noticed his back was swollen. I couldn't see any definition in his shoulder blades, his spine, etc, where you would normally see the outline of the bones. I had him turn over and his chest was swollen as well. His hands and feet are slightly swollen, but not near as much as his back and chest. It seems like there's fluid beneath his skin. Since we can control his blood pressure, he has meds for that, should we go to the ER anyway about the swelling and headaches? What could it be? He's never had anything like this before. He doesn't take any meds on a regular basis, and did nothing out of the ordinary yesterday or today, he's not overweight and has no big medical problems, just occasional high BP.
Thanks in advance for any help.
