I put this in the SF forum, so we would not get the usual, "Insurance is a rip off", "Insurance companies are crooks", type of post.
Recently a young lady posted she had been diagnosed with bursitis. After 4 weeks of rest it still hurt. She was asking, "is my hike over". Over Memorial weekend I hiked 50 miles, 20 in one day, and was worried, I might have done real damage to my foot. ( I'm OK, a couple of days rest and I'm 100%).
Anyway, for a person to hike when injured, to the point that they need surgery to get better, could be very costly. Once you have had surgery, some of the better health insurance companies, here in Georgia, will not cover that area, should you re-injure it. (This only applies to individual policies, not group health plans. It also only applies when you are purchasing a new policy. If you have an individual policy when you injure yourself the first time, they can not exclude future injuries.)
Hiking your way to the operating table might jeopardized future plans. It might prevent you from ever becoming self-employed, unless you are willing to be under-insured.
