You can do this if you have a legitimate doctors note and you are seeing a certified therapist. You might want to synch up your visits with plane flights or car travel to justify the massage to relieve the pain associated with work.
PS, please do not get greedy and put a 100 dollar tip for a one hour massage, that might throw up a RED FLAG.
This is all assuming that YOU are the SOLE PROPRIETOR of this business.
If you are not, I will definitely refrain from typing the next part of this post.
