I Was Diagnosed With Stage 1 Breast Cancer In February

I was diagnosed with Stage 1 breast cancer in February 2015. I had lumpectomy and radiation. Margins were clear, not in lymph nodes. Prescribed Arimidex, developed high blood pressure while going through this, always was normal prior to this year. Doctor prescribed Clonidine to help deal with side effects of hot flashes from Arimidex, having so many weird side effects and don't know what is causing what. Also, have a chronic pain condition due to severe bone loss/dental related on Norco two daily. Clonidine I believe is knocking me out so I can't take except at night. However, having other symptoms such as buzzing in ears, can't walk any long distances or I begin to drip sweat, feel light headed most days. I'm ready to ditch the Arimidex and Clonidine. Feel better when off both and not a lot of rebound from the blood pressure medicine. Any ideas?
