I had got chikangunya fever during December 2017, after that for about 3 months I suffered , now all of a sudden since two days I'm suffering from severe knee n ankle pain ( more pain only in the left limbs) swelling of ankles , I feel the pain from the day 1 when it started I'm unable to sleep at night because of the continuous pain, I'm a overweight person I agree but how can I resist this it is an terrible pain. I do work as a teacher I stand from 8: 15 in the morning till 4:15 since a month
