Hi, I've Been On HAART Since Last July. I'm Currently

Hi, I've been on HAART since last July. I'm currently undetectable. Which is great news. The past 2 months legs from the knees up are weak and hurts, unable to stand or walk for long periods. I also started having ringing in ears, primarily in the left ear. What can I do to alleviate these symptoms? Any advice is greatly appreciated. Thank you
