Just a side note about wounds, bad results, and doctors:
I recently attended the funeral of my brother-in-law. A few weeks before, he fell off a ladder and hurt his leg. X-rays didn't find a fracture; "treat it gently, you'll be ok." Time passes, and it still hurts. Orthopod (bone doctor) says "Let's take an MRI of that sore leg... Oh my! You have a non-displaced fracture!" So! Cast and bed rest; all is well, you'll be fine.
Within a week he fell down dead from pulmonary embolism. Basically, a blood clot went downstream from his leg and got filtered out by the lungs, thereby stopping them up. It turns out that deep vein thrombosis is caused most often in the legs by inactivity, lying prone, or extended sitting with poor blood circulation.
My personal belief is that if he had kept walking on it, living the uncomfortable to move but still active life, he might have been just fine, having never formed the blood clot that killed him. Since the doctor told him to stay off his feet in the fear that the hairline fracture might break all the way, I think that wasn't necessarily the best advice.
Of course, hindsight is 20-20, but pulmonary embolism is a common side effect among older folks with broken legs.
Bottom line: sometimes we get better in spite of what our doctors do for us. Results are better now than 200 years ago, but going to see the doctor isn't always the best choice. Other times, it is your only hope.
Yes, I have been self-treating myself for many years. But I also know more about medicine and medical necessicity than most folks. I have removed a full leg cast, 'cause it was a piece of crap that I didn't need, I have put in my own stitches, fixed cuts with superglue and sticky strips, and countless successful treatments with veterinary antibiotics. I seldom return to the doctor for stitch removal, and I really only go to the doctor/hospital when I know what is wrong and whether on not I can deal with it on my own. That being said, I am probably alive or at least not a serious cripple because of all of my medical rescues. I have also been misdiagnosed for fractured knee, collarbone, crushed lumbar vertebra, inguinal hernia, and i've had unnecessary facial surgery foisted off on me when I was too young to know it. So! Go see the doctor if you can afford it. Just keep your eyes & ears open, and get a second opinion if they don't give sensible advice.
