Hi, thanks for writing to HCM.
There are many possibilities for shoulder pain
in your case without any history of injury
. The pain could be arising from the shoulder joint proper or from the cervical spine
A detailed clinical examination and few investigations like Xray of the shoulder joint and an MRI
scan may be needed to establish the correct diagnosis.
As the pain is occuring only ocassionally, it may not have a serious underlying cause.
Hope this information is helpful. Good day
