All of the symptoms you're describing after exercising I had also. In the end, I found out I have severe small fiber neuropathy which often occurs with dysautonomia and autonomic neuropathy. I get the exact same symptoms after doing much of anything. You have to understand SFN to understand the effects on the small nerves and muscles. It is not laziness or just "pushing through" to exercise when you have SFN. The muscles can become starved for oxygen and blood causing more cramps, twitching, deep aching muscles, etc. Mine would last all night into the next day after just running the vacuum. I worked with a peripheral neuropathy PT doctor and started exercises at only 5 minutes twice a day and worked up from there. I can now walk further and a low dose of flexeril twice daily helps me do more without triggering symptoms. A neuromuscular doctor can help do a skin punch biopsy to diagnose you. I learned to rest after doing a little work. Put your feet up and let the blood get back to your muscles. Then you can do a little more again.
