Thanks for posting your query
From description it seems to be muscle strain
. As 2 and half months already passed, I suggest you to consult an orthopaedic Surgeon
for thorough examination. You may get a mri under his or her guidence. In interim, avoid forward bending, take antiinflammatory like ibuprofen
to reduce pain. Avoid heavy lifting and sternous activity.
