First of all, , I just want to commend you for taking care of yourself, using the crutches when you've needed to, and continuing to utilize the tools (one crutch) in order to keep yourself more comfortable - or keep yourself less uncomfortable at least. While I don't have personal experience with this, I think it's great that you are doing what you can and okay that the progress is slow.
Have you been able to talk with your doctor at all? I'm wondering if they would have additional exercises for you to do to help you feel more comfortable and balanced. I also wanted to share this article from one of our health leaders about using a mobility aid, https://psoriatic-arthritis.com/living/no-shame-using-mobility-aids.
Hopefully some of our community members can also share with you here about their experiences. I am wishing you continued strength, relief, and success with the crutch(es). Sending you gentle hugs. -- Warmly, Christine (Team Member)
