Hi.... It seems you had a very bad hit in your thigh. If I were you.. I would have had a x- ray done for my thigh tob rule out any fracture..may be a hairline.. I would do.. Lot of icing in the painful area frequently atleast 6-8 times in a day for next couple of days... Had my thigh wrapped with a compression bandage... I would like to give as much rest as possible...to the injured leg... Would have had any Anti inflammatory tabs given to me earlier... Apply some Anti inflammatory gel on too of my thigh... once pain gets reduced completely..I would gently stretch the frontvthugh muscles and ice it up for couple of days... Hope this is helpful for you... Kindly revert back in case you need any further help in this regard....
