Why didn't they tie the limb before an amputation in the olden days?

The procedure usually was done using an axe type instrument and they used rope or belts as a tourniquet to reduce bleeding. During the Civil War most of the soldiers died from post op infection for the doctors went from one patient to another, using the same axe or saw without sterilizing it.If the patients were lucky they were given alcohol until they ped out, although shock also was a blessing by also making them unconscious.Since there were so many injuries & the doctors had no training in repairing these severe injuries, they just cut off the limb instead of trying to save it.Even after the limb was cut off the patients often complained of "phantom pain" where they still had the feeling of pain in the missing part. This complaint is still felt today with amputations & the pain can be very severe despite pain medications.When the anesthesia wears off (or the alcohol) the pain will hit like before the surgery was done.Today we save the limbs if possible even doing microsurgery to repair & reattach blood vessels & nerves.Are you sure you aren't sleeping on your arm?The symptom kind of sounds like pressure on a nerve.If it continues have your MD check it out. Good luck.
