Hi,
thank you for providing the brief history of you.
A thorough musculoskeletal assessment is advised.
As the mechanism of
injury was the direct of the baseball on the leg, and now the area is painful and
sharp pain in the lower part of the leg, i will advice to undergo an x-ray if there is any bony injury. Usually, depending on the location the symptoms can be predicted, but as you mentioned that the ball hit the leg, it is tough to judge if the ball has hit the
nerve and leading to sharp pain.
Getting an x-ray and a clinical assessment will be good. If damage to any bone, muscle, tendon, nerve,
artery is there, one needs a hands on examination.
As you did icing and the pain is not coming down, you need to visit the doctor to get it check. Never ignore sports injuries, as one can never suspect the impact it does,
Usually, if no major signs are present, then with simple sport
physical therapy training , the candidate can go back to sport soon.
