<s>[INST] I am a female who was affected with polio at age 10 months and now am 29 years old, can my condition be fix by surgery without major complications? My left leg is weaker than my right leg which carry all my weight and whenever I gain a little weight over my usual 150lb I experience so much pain on my right waist when I stand or walk for a longer point of time. Please address my concern [/INST] Hello,Few minor changes can be made by surgery particularly, if there is issue with joints or polio associated joint degeneration then joint replacement can help.But entire muscle mass affected by polio cannot be reconstructed by surgery. </s>
