Muscle cramps and lactic acid in muscles

If it's happening the next day, what you're experiencing is DOMS - delayed onset muscle soreness. And lactate causes an immediate burn in the muscle as a way of forcing you to slow down and let your oxygen levels come up to a point where you can metabolize glucose normally.

I'm really doubtful that it has anything to do with your UC, but who knows. Since it's severe I'd see your GP/Internist about it and let him or her do some blood work and a physical exam to check for other causes too.

I'm been a runner all of my adult life and currently run about 25 miles a week, so I know that lactate burn well.

It's not the lactate that's causing the soreness, it's actual damage to the muscles. It takes a few days and an inflammatory response for the muscle to repair tears and other damage. The lactate and its metabolites (aka lactic acid) return to normal levels rapidly:

"Researchers who have examined lactate levels right after exercise found little correlation with the level of muscle soreness felt a few days later. This delayed-onset muscle soreness, or DOMS as it is called by exercise physiologists, is characterized by sometimes severe muscle tenderness as well as loss of strength and range of motion, usually reaching a peak 24 to 72 hours after the extreme exercise event."

Though the precise cause of DOMS is still unknown, most research points to actual muscle cell damage and an elevated release of various metabolites into the tissue surrounding the muscle cells. These responses to extreme exercise result in an inflammatory-repair response, leading to swelling and soreness that peaks a day or two after the event and resolves a few days later, depending on the severity of the damage."

I suppose it's possible that the inflammatory response in your muscles is somehow being triggered by your UC, but there may be other causes too. I'd look into it with your doctor if I were you.

i have noticed that since i started taking astaxanthin, i am way less sore. i used to get so sore from my workouts that it would last 3-4 days until i could work out again. i only do about 20 minutes of strength a day so i didn't know why my soreness was so bad.

maybe adding tonic water that has quinine in it?

methinks your perception of a flare has to change, for you're waiting for symptoms of increased inflammation,

I'd more worry about a consistent slow simmering rectum and colon inflammation than sore muscles. Although I hear you on the sore muscles on a daily basis, not from exercise, however.

You could consider massage or accupuncture to help ease the muscles...or stretching to help.
