[|Human|] female, 37.  I wrecked my motorcycle at a slow speed on 4/19/2011.  I was wearing  body armor jacket.  I took a hard blow to my left shoulder.  I sustained no damage...just sore.  Now, I have a lump about the size of a baseball on my left upper arm muscle...it limits me from reaching out and up with that arm.  Will it go away on its own?
[|AI|]  Hi, DEAR,Good Evening, Thanks for the query. Bump cause on your left arm muscle-is due to-Myomal tear-Muscle tear ? Or -Hematoma with resolving fibrosis.USG and X-ray would fix the cause of the lump. Treatment would depend on the cause-a-Your ER Surgeon would -a-Tear of the Muscle -could be if needed -repaired after excision of the lump.-b-Hematoma- could be Aspirated or could be Chat Doctor.  Hope this would help you to plan the treatment with your doctor. Wellcome for any further query in this regard. Wishing you good health. Good Night.
