Will An Umbilical Hernia Get Worse With Light Abs Work ?

I have an Umbilical Hernia. I went to my local Dr. and he said it could be stitched back together but it would probably come apart again. He didn't mention any other fix. I don't have health insurance and he knows it, so I think he was just trying to get me out the door after I just paid him $100 for nothing. I seen on line a mesh that could be put in. Is this something that works well? I am 38 years old, I workout 4-5 days a week, I weigh 202lbs and 5'11 tall. I don't smoke and I don't drink. I have a good muscular build with not much body fat. I take a lot of Vitamins and Creatine. I've had this Umbilical Hernia for about 3 years. If I'm not doing much its not very noticeable, But when I workout It is. I have almost stopped abs work because I don't know if this would make it worse. I like to lift very heavy. My bench is 315lbs for 5-8 reps and dead lift is 400lbs for 3-5 reps. I've tried to change my lifting to light weight and more reps, But I just didn't like it. My question is Will an Umbilical Hernia get worse with light abs work ? And should I find a Dr. to do the mesh fix?
