My 90 year old mother has peripheral neuropathy that mainly affects knee pain on her left leg due also to a visible hematoma present since her total knee replacement. She also has weak ankles from lack of conditioning exercise. Her podiatrist attributes most of her problem to poor posture walking since a lumbar spinal fusion at L2-3 5 years ago. She takes only 200 mg of gabapentin and 20 mg Tramadol once a day plus way too much Tylenol. For those who have peripheral neuropathy (knowing that doses are dependent on body weight) what is your daily dose of gabbys at what age and body weight? I have severe foot neuropathy from frostbite damage and at 250lbs take up to 1500 mg day. Presently mom only takes 200 mg a day at age 90 and 185 lbs with excessive leg lymphedema
