6 days ago I had severe pain and a hard, painful bump on top of left shoulder. 3 days later, the pain became agonizing and spread between my shoulder blades and through into my chest.  Saw GP who said take pain relief & anti-inflammatories and rest.  Its now a lot better, but the hard bump is still there - can you please explain what this might be?Many thanksSue Hill
Hi.it is best if you consult with a doctor, preferably a general surgeon, for medical and physical examination. Based from your description, it could be a cyst (a sebaceous or a gelatinous type). These lesions can occur anywhere in the body and have the tendency to recur.  Management (medical and surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
