Thanks for writing to us with your health concern. We sincerely apologize for the late reply.
I have read your query.
It looks to be hamstring strain.But to confirm this please answer some questions-
-Is there any swelling.
-Is this pain increases on walking or stretching your leg?
-Is there difficulty in walking?
-Is there any discoloration at back of your thigh?
Hamstring injuries can be very painful. So i advise you to rest completely for the next one week or so. You can try applying some anti-inflammatory spray like volini/Relispray or any other local brand that is available. It will help in reducing the inflammation inside. Also for quicker pain relief, you can use Tab. Diclofenac twice a day after food. Once you reply, i will be able to guide you further.
We once again apologize for the late reply,
