Welcome back Pete!! I admit its a little after 6:00 am my time in Tx and I have been up all night-so I am a little rummy lol. I must admit reading your post gave me a laugh. It was almost like reading something out of a comic book lol. Black bear and all. Glad you are home safe and sound. Give yourself some time to rest up. I have an idea for you, something that may help you. Try soaking in a hot bath wth apple cider vinegar. Very good for muscular things. about two cups in a tub of water. I know its a pain carting your Mom back and forth, just be greatful she is alive and able to care for herself.
I fell a week ago and broke my left arm. Nowing waiting on the swelling to go down so a caste can be put on it. that was a pain.
Take it easy a day and be kind to your body, its the only one you will ever have.
