During residency, I had a 39 year old female patient with back pain (what else?) who was also trying to get pregnant. She had no kids yet. I wrote her a prescription for a strong NSAID and told her, "Don't take it if you think you could be pregnant!" (The attending originally told her it was probably okay, but it's Class D, so not okay!)
She told me that she decided to put off trying to conceive until her back pain was resolved. The attending said that was probably a good idea.
I held my tongue, but I wanted to tell her to have the baby now and deal with the back pain later. She's almost 40! And it's not like back pain is something that goes away quick. We had patients with back pain since before I was born! It's not like she's waiting for a papercut to heal up. The back pain will still be waiting for her nine months from now.
As usual, I kept my mouth shut though.
