@janie6696 Hello and thank you for joining the conversation. Good for you for no longer wanting steroid injections. It certainly sounds like your body has been damaged enough and now could benefit from calming your central nervous system. Your goal of walking 5 minutes is a perfect place to start.
I commend you on recognizing your sedentary lifestyle and its contributions to your debilitations. Behavioral changes no matter your feelings or thoughts is what helps get the ball rolling. Practicing behavior daily, such as eating, breathing and exercise, helps to become habitual.
Graded exposure is used to assist in tackling feared situations, activities or objects due to anxiety, such as walking for 5 minutes. Perhaps you add 1 more minute the next day or every other day, or after a few days. Ease into what your body allows until you can gradually build to find your plateau.
During my sedentary time and deconditioning I used my small driveway to walk. I started slow and added 1 more lap as I could. Nature is great distraction, along with fresh air. Are you able to get outdoors to walk? How has your goal of walking 5 minutes been going?
My walking is going well, but will end once it gets slippery outside - which it does every winter. Here in NH winter has delayed this season which is a help. I do have a tread mill that I use during these times. Thank you for your encouragement.
