Coconut oil and muscle rub

I have been massaging for a month and a half now. I started using just coconut oil (I'm out of my tea tree and lavender oils). I have gained about an inch in this time. I was wondering if itd be okay to massage w the coconut oil in the am and then use muscle rub in the pm. I've read some posts on here where some claim the muscle rub gives really good swelling. My fiance has back issues, so we always have plenty of rub laying around. I thought of using the coconut oil and then applying the muscle rub, but that might just be messy, and the oil would probably block the rub from absorbing.
