Ok so about a week ago my girlfriend noticed a minor pain in her shoulder, which is constant and never relents. The day after she noticed the pain her leg was in so much pain to the point she could not stand up but it eventually got better but her shoulder still hurts constantly even with tylenol. She is a swimmer and slightly overwieght, shes 5'8 at about 160LBs I thought it was just too much phsycial activity but she has a lump on her right shoulder just between her deltoid and clavicle. She says its getting worse, but I just want to make sure its not cancer or a cyst or something like that.
If anyone has any suggestions as to what this may be I'd appreciate it thank you.
