This may sound like a stupid question, but aside from outright ligament tears, or cartilage breaks, what causes joints to be sore or stiff after a workout?
What part of the joint actually does the hurting? Where are the painful nerves? In ligaments? tendon attachments? cartilage? or something else?
Does cartilage even feel pain? If it has such a poor blood supply can it even have nerves?
Is stiffness or swelling just the joint filling with fluid or is there actually a lubrication issue?
Just curious if anyone actually has some good information.
I know anti inflammatory help, but what is actually inflaming?
Which leads to the real question, serious injury aside, what helps joint be "looser"?
Why my knees and joints hurt when I crawl out of bed in the morning but are fine after a workout (until later)?
Thanks in advance.
