I'm so glad you are okay, Bobby!

I can't get in or out of the tub, and I'm really afraid of falling in the shower.

I would at least get a non-slip mat, or those non-slip stickers for the bottom of the tub regardless of what the issue was... you can never be too safe.

As others have suggested, it couldn't hurt to have someone help look for ways to make you safer in the bathroom. Your mobility may have changed since the last occupational therapist assessed you. You can ask your PT to help you. He may recommend another occupational therapist come in. They can suggest items to order.

That massage stick may "hurt so good" you will want to use it a lot!
