my muscles are extremely tight on one side of my body. It's hard to walk 
That's interesting. Only one side of my body is affected also.
My left side is much more affected, more painful. I do also have some muscle pain on right side. Possibly due to an old injury I had to the left side. Benzo withdrawal seems to have more effect on areas in the body that have been injured before.
This has been one of my symptoms, especially in my second and this last withdrawal. During the second withdrawal I did not associate the pain in my hips, piriformis muscles with withdrawal from Lorazepam, but I really think that is what it was. I had an old injury from falling down the steps decades ago that caused me re-occurring sacro-iliac problems, especially when I worked since my job is very physical. Anyway, to make a very long story short, I think that my psoas (deep abdominal ) muscles go into spasms during waves and pull my sacrum/pelvis out of position. This has been happening since I first took Lorazepam and cold turkeyed. I thought I had an unstable pelvis and had injections, physical therapy again and again and I kept having problems with it.
Until last year when I went to a myofascial massage therapist as a last resort since I had tried just about everything else--I didn't even know what the psoas muscle was! But he released the muscles that were in spasm, and there were a lot of various muscles in spasm in my body and now I can do it at home by myself.
The muscle pain finally went away last year over the summer, and I even ran a 10k race. But then I got slammed in November with an acute-like wave that I am still recovering from. All the fibromyalgia-like pain came back--especially in my left shoulder blade to where I can't sleep on my left side at night because my neck starts to spasm. Also in my left hip the muscles and tissue around the joint is very sore, also piriformis, and gluteal muscles are very sore. I roll around on a trigger point release ball and it helps. Also use a moist heat pad. I really thought I was done with all the pain symptoms and I did have a few blissful months without it, but now it is back. Needless to say, I had to stop running last November. But I am up to a fast walk now.
The question I have is, is there really inflammation going on with these muscles or is it neurological in nature? Because I will have severe pain in my right triceps for a few hours and then it will be gone in a few hours. This is another area that I injured skiing 3 years ago and I also ended up with frozen shoulder from that fall. Excruciating pain working through frozen shoulder at physical therapy.
The muscles in my chest area also tend to get really sore--and sometimes it feels like they are in spasms. My chest gets really tight and it affects my breathing too. I also get pain in the tissues between my ribs and around my sternum--costochondritis.. I will get sharp twinges in my front rib cage and around the sides too. Mostly on the left side, again.
So I suppose there is one silver lining in this for me--no more sacro iliac problems! In the past my pelvis would go out and I could barely walk. So many sessions at the physical therapist over the decades. As long as I keep my psoas muscles stretched every day (and it only takes a few minutes twice a day) they are not pulling my pelvis out of position.
I was taking turmeric last year but I stopped when I got slammed with this wave--I thought it was revving me up, but I don't know for sure. I may try to add it back in again--I really don't know to what extent it relieved the muscle pain for me last year. For whatever reason, the pain did go away only to return.
