Tick41 I dealt with this for decades, even when I was in 'remission'. However, I was mistakenly living with the idea I had Fibro and chronic fatigue syndrome, so the reasons for this outcome from exercise (or heavy physical labor) were bogus.
I had to manage this with self-employment and learned to either moderate my activities or be prepared to be tanked out the next day, often in pain, but always with exhaustion.
Now that I know I am cdc pos for RMSF, and am sure I had Lyme and co., all along, I have a few theories of what was happening.
1. My muscles heated up with work, which made the invading organisms uncomfortable and actively doing damage trying to cool their environment down.
2. What bluelyme suggested about
damaged red blood cells, insufficiently able to deliver oxygen to our muscles. Wouldn't they cramp form that? What other natural process would be affected by lack of oxygen while heavy exercise?
3. The disease organisms are damaging our soft tissues, protective coverings on them and our nerve fibers faster than our body can repair itself. Minute tears happen naturally anyway when we heavily call on our muscles. Our naturally rapid repairing process is impeded by the workings of the disease.
