I am a 60 year old women athlete. I completed a 1/2 ironman in May . I have a small umbilical hernia. There is no pain, but when run my hand across by stomach above my belly button, it sticks out. My doctor wants to "keep an eye on it" and check it again in 3 months. Can I continue with weight training, swimming, running, and bicycle riding? The doctor seemed extremely vague about what training I could continue. Is there anything I can do to keep from having surgery?
