I would suggest icing the knees instead of applying heat. That can help reduce the inflammation and pain caused by the extra weight she is now carrying every day.
I put a mixture of 2/3 water and 1/3 rubbing alcohol in a zip-lock bag and keep it in the freezer all the time. Then when I need to ice a joint or muscle I wrap the bag in a hand towel and apply the ice pack that way.
Also, I hope your sister is sitting down and elevating her feet whenever she can. This helps reduce swelling and pain also.
Well, thanks for guiding. I Would really try for ice therapy. Hope this would result in getting an improved sleep which she needs at this stage.
