Hi Teresa @hopeful33250, I think you might want to try a different type of face mask. I saw this article discussing the problem you are having.

"If you wear behind-the-ear hearing aids, you may encounter problems trying to wear a standard face mask with elastic ear loops. The loops may tug at the wire or tube that goes from the body of the hearing aid down to your ear. You also may inadvertently pull your hearing aids out and lose them when removing your mask."

The article above links to this one - A Design Fix for Face Masks: https://hearinghealthfoundation.org/blogs/a-design-fix-for-face-masks

Hope this helps....
