Foods that prevent muscle tearing (side effect of antibiotic

I need some help. A course of antibiotics I just completed have some nasty side effects related to muscle injury/ detachment/ loss and tendon injury/detachment. Some of the reviewers describe a popping in their joints weeks after taking the medication that is followed by injuries. The popping is happening in my joints as well as other side effects from this drug (nausea and insomnia. Fun, right?), so I'm very concerned I'll experience this other side effect. I did not know about this when I began the antibiotics, and, honestly I was so very sick at the time I don't think I cared to check. But now that I know, I'm curious if there's something I can be doing to battle this side effect. I'm assuming that the meds were sucking some nutrient out of my muscles/tendons that they need to function, but since I'm still new at this nutrition/ body chemistry thing, I need some help with this one.

What nutrients am I looking for and what foods/ supplements can help with this? Thank you so much!

For the next 10 days for sure, I'll be limiting my intensity on the treadmill at home and stretching as much as possible. Anything else I might be missing? I really do not need to get an injury to set me back!
