My grandmother has red and swollen hands and feet. ONLY hands and feet! She said that she cant feel any itchy,burning etc. feeling. She said that it doesn't really bother her. We have no idea what could have caused it or what it could be. Here are some pictures:

Not sure for how long have this has been going on but I think for about a week or more. We have brought her to the doctor and we are waiting for the results but I just thought of posting it here to see if anybody knows what it is and how to cure it. Please help! Thank you so much!
