Recommend Medicines For Chikungunya With Joint Pain

Hi, I am suffering from chikangunia since last 3 months. I get pain in my joints & it is very severe during morning & when I have to get up after sitting continously in one place. Can you recommend some medicine for the same. Currently I am taking Myoril 8mg since last 8 days. Is it safe to continue with this drug? or can u Rx some other drug?
