My thigh muscle snapped, then owwww

[CalicoBlue]

Took a step off a train this morning and my thigh muscle seemed to snap and a horrid pain. Been bad all day, can hardly walk downstairs. Has anyone else had this? does it just go on its own?

I get this in my knees sometimes and it goes away - not sure what it is - start of arthritis maybe? GP if it doesn't go away.

Sounds like a pulled muscle. Assume it was the front thigh muscle and not the back?

It should be better in a few days, if not see GP.
Good luck
