This year I've found out I have hypothyroidism, I am B12 deficient, I have had to have a hysterectomy recently. About two weeks after I had my surgery, I started having pain under my right rib cage. This is most noticeable when I am in a sitting position. The pain radiates down to my waist and to my back. It feels like there is something there. Like a brick or something. Mostly its just a sore feeling, but sometimes it is quite painful. I went to the dr and a CT scan was ordered but it came back normal except for a 9 mm lesion on the liver they think is likely a cyst and a 3 mm nodule on my right lung. They say this is not causing my pain. I don't know what it could be. I did used to be a heavy marijuana smoker for 13 years. I do have a history of colon cancer in my family. I lost both my brother and my grandfather to this last year. I have had a colonoscopy but it was clear. I also have a history of Migraines and take Trokendi XR every day to prevent them. I also have issues with mood and take meds to stablize that. I am going for a second opinion. What question for I be asking? And has anyone had a similar experience?
