Time Will Tell

So Mom is in a rehab facility. They had her up for PT this morning and it caused her blood pressure to drop, she turned white and nearly fainted.  They put her back on bedrest and will try again tomorrow.  

I tried asking her about it, she said her leg was "stiff".  Yesterday she was able to use her walker from the bed to the bathroom. Today it was difficult to stand, walking was out of the question. 

I don't know what all of this means for her health. Its one of those niggling worries.

Time will tell.
