Dont worry about MND. Believe me. We've all had this stuff. I couldn't even walk on my hard surface floor for a few months without foot pain. We joke that we are like 90 year old grandmas and grandpas sometimes. Its just how BFS goes. The great thing is that almost everything seems to be temporary. Then it moves on to something else. So rest your mind. Its par for the course. Things will come and go. Even new stuff will pop up, hang around a few weeks, then disappear. Each time you might be tempted to think you've got the worst version of whatever disease matches that symptom. That's what most of us do here. But try to remember that BFS is the "great mimicker". It presents as 30 different diseases, and then says "Just kidding!" and the presentation changes to something new. Keep exercising. But do not push hard. Do a very light workout at the most. The goal should be to flex all muscle groups in the body. I would go to each machine in the gym, set the weight low, and work out that muscle group. Ultimately hitting the whole body. This is very important to continue doing. Exercise has been my savior in all of this. But do not over-train. Only push weight that is easy, and gets the blood flowing. Whole body. Then collapse on your bed and rest. I usually had to wait 2-4 days between these "grandpa" workouts just to rest. So stick with it, and after some iterations of this cycle, you should start to feel a little better. Nothing reduces stress, inflammation, tension, and countless other symptoms like exercise. Please do not be like some here who still "kill it" at the gym. Or who insist on "distance running" or cycling. Your body needs a break. Its telling you to stop. Give it a chance to recover. -B-
