Suggest Treatment For Muscle Twinges, Pain In My Muscles, And Stiff Joints While Having Anxiety Disorder

Question:
I have muscle twinges, pain in my muscles, stiff joints. I suffer from anxiety disorder, and I am an admitted hypochondriac age 51. I take klonipin, Nexium, statins for cholesterol. Of course, I'm worried I have either MS or ALS. During my latest anxiety attack, I had a massive squeezing sensation around my ribs, could that be anxiety or the MS hug? I have no visual problems. My shoulders and hips are more stiff than anything, but I have joint pain in hands, possibly arthritic. The twitches have been going on for about a month. They started in my abdomen, I went back on klonipin, and they quieted immediately, but now they are in my legs and rib cage. The fear of ALS has me practically paralyzed in fear. Before, the twinges in my abdomen felt so strong they were like pregnancy, but I'm not, of course, but that was my fear for weeks until the klonipin quieted it. Now I've moved on to ALS from pregnancy. Is there a definitive symptom we can talk about. I have two college degrees, and they are in a medical field, so I spend hours on Google worsening my anxiety and fear of ALS. Please help me.
