Well - I had a busy morning and it still goes on. We took MIL back to the ER this morning. Yesterday, after the errands she & I did, when she got home, she was getting undressed to relax in her night clothes (no working A/C) and when taking off her socks, she got one off with no problem, but when moving her leg to get the other off, she heard this massive *pop!!!* and her knee was in excruciating pain. She can not put any weight on it, and last night she could not bend it at all. This morning it was able to bend, but she was afraid something happened to the joint and it is a knee replacement joint. So, back to the ER we went and they all know her by now very well. She had x-rays done and nothing is broken or out of place. She has very bad arthritis and the ER doc recommends that she be placed in a wheelchair now. He will send the recommendations to her PCP and we will see. Problem is, her house is old enough that the doorways are not wide enough for a wheelchair. We will see what happens from here. Later, we are going to Olive Garden for son's birthday dinner.
