If you give it a year, I think there’s a good chance that most of your symptoms can go away on its own, so long as you do not aggravate it by taking anything or eating anything in large enough amounts to cause a significant anti-androgenic effect. I’ve learned that from experience. Initially I had stiffness in all my extremities, arms, and legs. It started with this constant tingling in my nerves in my legs and arms. I was dragging when I walked and had trouble even typing or holding onto heavier objects. I lost a lot of strength as well. Things normalized though for the most part. At least that was my experience.
Some parts of my body feel permanently contracted and can’t relax. Sometimes there is pain. One part of my body gets painful when I try to use it, feels like trying to stretch a rubberband that is already stretched. I usually don’t feel this stiffness in the rest of my body unless there’s stress or I’ve eaten or taken something that I shouldn’t have.
It’s not similar to Parkinson’s, but Kennedy’s Disease. It is indeed scary but give it some time. Things do usually get better on their own. One thing you don’t want to do is experiment with things you don’t understand. I took something called an NAD booster that caused something unthinkable, while others benefit from it here. It’s Russian roulette. If you think muscular dystrophy in your limbs is bad, I developed it in the swallowing muscles in my throat. My diet is radically changed and I have to constantly purge food, liquids, saliva out of my trachea by coughing until I almost pass out for hours every day. See, I actually look back on when I complained about my limb stiffness and think life was livable. I actually had it good compared to now lol.
For now just try to take it one day or one month at a time. Some days you’ll feel better, other times you’ll feel like you haven’t improved at all, then one day you may just forget the worst of it, but just remember that from now on you’ll have to vet whatever medication or supplement you want to put in your body.
Also strangely meditation helps with the muscle stiffness, give that a shot.
