question: Hi. I m female, 40, had surgery and was treated with radiation for a 2.5 cm ductal carcinoma with micro mets last year through the end of November. I ve started working out again over the last 3 weeks. About one week ago, I noticed pain in my upper abdomen, about an inch below the juncture for my ribs. Sometimes, I just randomly feel pain, and always I feel it if I arch my back a little. This morning I noticed that I have a lump there. It feels like a nodule resting on top of a vein. It also hurts if I lightly rub down on the nodule. I m not sure if I should go to which doctor... I have a lot right now.
