Hello and welcome to Living With PsA! I’m sorry to hear that you’ve been forced to cut back on your level of activity - but as you mentioned, swimming still remains a very viable and fun (at least in my opinion) option! I hope the adjustments in your medication will ultimately let you improve on the pain you experience during mobility. In the meantime, you’ve come to a great place to share your experiences and also do something that doesn’t require to much effort or movement. I encourage you to start getting involved in discussions so that you can meet our many wonderful members - and the “How To Use This Site” tab up top provides some useful tips.
Good luck, and don’t hesitate to contact me with any further questions!
