forearms haven't had an issue since, but that will probably change tomorrow. My left tricep is doing it now though. It's literally twitching at full extension, then locking up.
You should get a good deep tissue massage. It sounds like you've got a lot of junk in the fascia everywhere.

These are back again, went away for a while. 100x worse this time they just lock up and i cant do anything.
