My husband has moderate to severe pain under his left shoulder a little towards the right. This has been going on for approximately 3 months. It is some what swollen and is also tender to the touch. Motrin 800 takes the edge off the pain, cold compresses do not help but heat seems to give him some relief. He has seen a physician and was given muscle relaxers and narcotic pain medication that really just puts him to sleep. He also has taken steroids which did seem to help him. It is also important to note that on December 5, 2014 he was diagnosed with breast cancer in his right breast and is scheduled for surgery this Thursday 1/22/15. Pet scan, CT scan, MRI, Ultrasound have all been negative for any cancer in the area where he is experiencing the pain in his back. What are your thoughts? Y. Williams
