### input:
I have intermittent bone pain in 5 specific areas. It has been going on for over a year but seems to be getting more intense and more frequent. The bones affected are my right ulna, left humorous, right femur, left foot and pelvic bone. It is stabbing, sometimes throbbing pain that can be very intense and then it just goes away. i had a terrible ear infection recently that took 6 weeks to heal. We finally figured out that the infection likely started in my in my mastoid bone. I was treated for mastoiditis and have no idea if that is related or not. I am a 37 year old female that is otherwise in good heath. I have 5 children and am very active. Two recent blood tests showed elevated bilirubin and blood in my urine but a liver work up showed nothing. That was about 10 months ago.We recently moved to a new state. The bone pain is getting worse and I would like to see a doctor. I am worried I may have bone cancer or something serious. I don t want to go into a new doctor and demand testing, but what is the best way for me to encourage my doctor to rule out anything serious?

### output:

Hi, Thanks for writing in. Bone cancer might involve any bone and rarely also affect multiple bones. The usual signs of bone cancer are swelling which is sudden in onset and rapidly progressive with pain in the region. Some bone cancers can also cause signs of inflammation in the region. Since you have been diagnosed to have mastitis therefore it is almost certain that your condition is infective in nature. Mastitis occurs due to chronic infection of the middle ear which involves the mastoid bone. Treat with medicines is recommended and in some patients surgical treatment is required, and it is not a bone cancer. Please do not worry.
