In 2012 I had treated with interferon and ribavirin (and victrelis)for hepatitis C, stopped treatment due to optic nerve damage in one eye.

Afterward, I started having muscle stiffness and pain, mainly in my back.

I exercise daily, suppliments I take include magnesium citrate, and niacinamide.

A while back my doctor had me take an x-ray which of course did not yield any useful information.

I do have a prescription for baclofen, which does help to a point. Thankfully the baclofen doesn't make me drowsy, like my previous tx with methocarbamol did.

Anyone have such muscle stiffness and pain?

Any ideas as to what a cause could be?

Suggestions for better relief from the muscle stiffness and pain?
