I ride with a physiologist who researched this sort of thing, using dogs (and he loves dogs, but it is what it is). He told me that lactate has nothing to do with anything, pain-wise. One gets the lactate burn, but it's not the lactate that's causing the burn, it's another chemical. Which in any case has nothing to do with our subject, muscle soreness, which as explained in the link, is caused by damage, nothing to do with what we feel during exercise, just DOMS.
From my reading, the cause of DOMS is still unknown and the micro-tear hypothesis of muscle hypertrophy and strengthening seems to have less and less support. Micro tearing occurs, but does not seem to be necessary for the response. No time to pull literature now. Maybe later.
It seems to be the H+ ion associated with lactate that stimulates pain muscle pain receptors during exercise.
