I completed 5 sessions of radiotherapy a month ago. Had surgery (lumpectomy last November). Was told I would have a reaction 2 weeks after the radiotherapy. No reaction. At 4 weeks suddenly my ribcage very painful. Could not lay on either side in bed and even laid on my back very uncomfortable. Decided to stop the letrazole I had been taking for 4 months. Immediately the next day symptoms lessened then within a couple of days much improved. Stomach felt very sore. Gradually over next few days went away. Now have a sore left wrist with intermittent pain. Also various spots of pain in other parts of my body. Not sure if it was a reaction to the radiotherapy or a reaction to the letrazole or both. Staying off the letrazole and will see how I go. What do others think?
