From Nov 04th 2020 onwards i was complaning doctor that my left leg is paining then doctor suggested me to take rest till 6 months.from january onwards i am trying to contact doctor, i texted him, called him not even a single time doctor responded me.i called many times since january.now i cant even walk properly, even sleep properly.24 hours is pains on my left leg which is a new problem after surgery.
I think doctor has done some mistake during surgery.
