If you’re in doubt, it’s probably best to see a physiotherapist first. Massage is a maintenance and self care tool, but it might not get to the reason behind why you feel an area needs some attention. If an area feels stiff or sore, seeing the physio will allow them to assess and diagnose the issue, and figure out if massage is appropriate. Often people can jump into a massage a bit too early, and end up making their issue worse.
Once your issue is stable and safe, then asking your physio if you're ready to see a massage therapist can really help with longer term maintenance. It’s often a nice reward for a job well done after a month of diligent rehab. As with all hands on treatment, remember that the massage is a cherry on the top of your plan, the bulk of your management should be homework!
