Hi All, I've just been surfing the net and come across an article about stain induced fibromyalgia! I knew statins caused muscle pain but as I had been on Amitriptyline for 4 years before being put on Simvastatin I didn't think THEY were making my pain any worse. Seems like perhaps they were because I've now been off statins for 14 months and have very little pain on a regular basis unless I overdo things. I noticed the improvement after 10 months when my achillies tendonitus also cleared up after 2 years of not getting better. I also came off amitriptyline in the last year (which wasn't easy) because I felt so ill. Now my only problem seems to be that I can't sleep as discussed in my other blog. I'm now wondering if the statins were causing most of the side effects I blamed on the amitriptyline!? Don't know if I should risk going back on the amitriptyline so as I can get a good nights sleep? I feel torn as I obviously don't want any side effects back but I'm so tired!
