It seems to be the H+ ion associated with lactate that stimulates pain muscle pain receptors during exercise.
Thanks. I found this over on Quora: "
The real cause of sore muscles, hours and days after extreme exercise, is the influx of fluids, prostaglandins, and white bloods cells, to the muscle area in an effort to repair the damaged tissue." Like you say. I wonder how this produces nerve signals, but I wonder about a lot of things. HMB, which reduces muscle soreness, rather than speeding muscle repair seems to reduce muscle breakdown in the first place, which fits.
