Your fish should be OK, it might slow your HSB's growth down temporarily while it heals up though. Typically hooks will rust out rather than get dissolved by acid. I have seen a LMB pass a jig with the curly tail still attached to it out at our pond. Chrome plated hooks are the one type of hook I do not like to leave in as they don't rust easily. I base this on expierence since one October I left chrome plated worm hook in a LMB's throat, the follow April I caught the same fish again and the hook was still in it's throat, the hook had barely began to rust. The good news was that the hook was now turned around and I could easily remove it, but that was one skinny LMB after 5-6 months with the hook in it's throat.
