Welcome at HCM.
I have read complete details of your question.
It looks that you are having strain of 2nddegree in your adductor muscles of thigh.
You should do following to have relief in this-
-Avoid strain on your limb.
-Take a good analgesic
-Do cold fomentation ,if this injury
is recent or warm fomentation if there is no swelling .
-Check for presence of swelling or redness
at your thigh,if it is there then consult to your doctor.
Hope this all will help you.
With best wishes.
