Thanks for the query to H.C.M. Forum.
This is not to disease but known as exertion contusion
( collection of mass & blood in simple language).
Regular exercise after few days rest will provide complete relief.
Get a rest of 5-7 days and start again.
If still feel inconvenient then take 1-2 pain killers along serratiopeptidase
(reduce edema ).
Ice pack massage
In my opinion this is not a cause of concern as this is a sports related contusion. resolves spontaneously.
