I had Chikungunya in 2015 and it was a very very slow process of recovery. I can say that even till date , I have not recovered to the extent of 100 percent. I get pain in muscles/joints occasionally even now. My experience is that conventional medicine does not have good solutions for the speedy cure from this problem. I have not tried Ayurvedic treatment and cannot say if that could work better.
I recovered substantially from the effects of Chikungunya in about 18 months after it occurred. After that , the episodes of pain tapered off but I can say have not died down completely. I can say the effects have died down to the extent of 90 percent.
