I am a 73 year old female. I have left side chest pain, burping, nauseous, neck and back pain. Recently, have had a right breast lump removed that was diagnosed as cancer, no cancer cells in lymph nodes, staph infection of surgical lesions in breast and lower right arm area. Infection being treated with amoxicillin. Recently treated for pain in cervical vertebra, the back and neck pain have persisted for 2 years following a total knee replacement. Neck and back pain worsen by 6-8 pm every day. Knee that has been replaced continues with mild to moderate pain.
