big toe joint

[car10002]

hi everyone

was wondering what would cause stiffness and a occasional bit of pain in left big toe joint.

sometimes have a little bit of pain in left big toe joint at bottom of toe joining to foot, sometimes it happens certain days, sometimes its when you put pressure on it or squat or both and usually ok once you stretch it or rest.

is there a way to stop/relieve the pain or stiffness.

also have a question about upper back pain or discomfort.

what would cause upper back pain or discomfort, usually when you put heat on it its usually good again but wondered what generally causes that and how to relieve or stop it.

also what causes knee pain on side or behind knee cap for someone, usually when you or they put heat on it its usually ok, how would one relieve that or stop it
