lupus shows up in all forms but me personally I have the swelling in my legs and feet but not to that extent of your sister. I just wanted to say it is great you are so supportive of your sister, you will see that from a lot of us on here some of our family members are not very supportive of our disease. My twin sister hates my lupus, before she moved out she resented me for it and told me she hated me. Since she moved out it's gotten better but she still is very rude about my lupus and throws it back in my face if we fight so I try not to ever bring up my lupus with her. I told you that story because I would love my sister to care for me and be as understanding with me when dealing with my disease as you are. I think that makes you a pretty great person to be as understanding and caring with your sisters lupus. I hope she continues to keep getting better and if you or your sister needs to talk to any other lupus people please come back to WHL.
