Weird thing last night. Yesterday afternoon, I did an advocated SUP lesson and the instructor really got me working my core muscles.
Then in the evening win the way back, we stopped at Pizza Express at Cobham services on the M25. I was prepared to spend the rest of the trip back in pain, because I pretty much always get abdominal pain after eating a meal.
But it didn't hurt. I felt full, but without pain, and this is a vanishingly rare experience for me. Eating = pain. It's always been like that, and I basically expect it.
Except not last night.
Meanwhile this morning, I have massive stiffness in my abdominal muscles.
Kinds feels like too much to be mere coincidence.
