Twolane,
Hope your Mother recovers and does well. My Mother had similar symptoms and recovered.
Lightning does some strange things. Our house did catch fire on the peak of the eve. For a couple of years afterward we would still find things like receptacles at the other end of the house that had arced and burnt. From your description, sounds like your service entrance took the brunt of the strike.
I am sure you already know, but with everything you have had going on here is a list of things we later found problems with and some we did not immediately check out:
All appliances, dimmers and low voltage lighting systems, sump pumps, stereo, TV, cable and sat boxes, phone wires, wireless phones, computers, modems, routers, lawn sprinklers, softeners, furnace and air, water heaters, ground fault and arc fault breakers, pool and spa tub breakers and equipment, fluorescent lighting ballast.
Hope you get back to normal soon.
