Dear friend, welcome and thanks for entrusting your query here at HCM !
Good to read that there is no fracture
Then there is not much worry.
You could be right in thinking of a bleed (hematoma
)in the muscle there. It takes weeks to get reabsorbed and organised.
So the hardness you can feel.
One can see for a hematoma on an ultrasound
of the thigh.
If you are too much concerned, you can be sure with an ultrasound. You can continue with OTC pain killers.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries.
Thank you and Good luck !
