I live in the dominican republic and play masters league softball about 3 times a week -2 games a day-. For about the past 2-3 months i have had a chronically stiff neck, and experienced significant muscle heaviness, like a resistance keeping me from lifting especially my right arm, although i can still lift it but i can feel the difference. I can't do pushups now either and could do about 30 at a time before. this all starated after i was out of action for about 2 months, sedentary with foot elevated, because of an ankle injury and have since stopped going to the gym. I feel like i have much less energy, although I do feel very strong, and was wondering if this could be due to some sort of neuromuscular effect the injections might be having or perhaps its the benzyl alcohol or some other ingredient in the injections. Please don't tell me i,m just getting old!
Thanks
