In June of 2016 I was diagnosed with stage 4 kidney cancer . The only way it was found was I was having very bad pain in my back that I could not lift my right leg. I went to the er and the did ct scan and found that I had kidney stones in the tubes. dr said I need to see a kidney dr. he said it look like it was all contained in the right kidney and it was not in the tubes. They removed my right kidney when test came back he said I had a very aggressive stage 4 cancer and I will need to be watched every 3 months for 5 years. My question is for last week I have had very bad pain in my bladder area it kinda feels like period pains and it hurts all the way through to my back . I don t understand I have had a full hysto. I am scared the cancer has moved to my bladder can you tell me what kind of pain do u have with bladder cancer? I have not got in to see my dr yet and I am super worried.
