I went to Mexico and had a great experience. I've actually been to Mexico for two different surgeries and both times I received excellent care. If money is tight and time isn't of the essence, then you could try to go through your insurance again now that you have been diagnosed with a comorbidity. If you have the money and would prefer to not have to wait to jump through all the hoops with your insurance, then Mexico is a good option. Just make sure you do your research and choose a surgeon you are comfortable and confident with.
