I can walk down stairs without using a handrail.
I have sometimes ab cramps to the second part of the muscle from top, on my right side. They are terrible. The muscle gets so tense that it sticks out and it's like being stabbed - or how I imagine being stabbed is. I usually have to lie down and stretch backwards massaging the little fucker. Horrible.
Pain goes away prestty soon after the cramps have gone. The muscle remains a bit stiff and still prone to cramps for a while though. Maybe for a day or two I have to be careful when sitting up, or putting climbing shoes on and the likes. Moves where you curl and pull are to be avoided.
