Do you already have a follow-up appointment scheduled? When someone gets the implant, it's usual for the healthcare provider to schedule a follow-up to check that everything's okay several weeks later. If you don't already have that scheduled soon, it's a good idea to contact the provider who did your implant and arrange one.
A follow-up appointment is exactly the right time to bring up this kind of issue with a healthcare provider. A provider who's trained in implant insertion can check it for you and judge whether everything's okay, based on what they feel and what you describe to them. Sometimes our body can still be a bit sore some time after a minor procedure, and it's possible that that's what you're feeling; or, rarely, an implant can move slightly in the arm to a place where it isn't comfortable. A healthcare provider should be able to advise you about what best to do.
Obviously, if the pain gets any worse or you have any other symptoms, you should see a healthcare provider as soon as you can, and not wait days or weeks for a regular follow-up.
If it did turn out that this implant needed moving, you can still likely use the implant as a method if you wanted to: likely, a healthcare provider would be able to put a new one in at the same time as removing the old one, in a slightly different position. Again, you'd just want to ask the provider about your options and let them know what you want
