However, depending on the specific context, you could use:
* Rec. - This is sometimes used in a medical context, but it's not very common.
* Recov. - This is a more formal abbreviation, but it's not as widely used as "rec."
* Rcvry. - This is a less common abbreviation, but it's sometimes used in technical contexts.
It's important to choose an abbreviation that is clear and understandable to your audience. If you're unsure, it's always best to use the full word.
