I was just checking in to see if natur-throid is still on back order right now and if anyone has heard if it will be back in production in 90 days. I have been on levo and cytomel for a couple weeks and ever since I have been on it I have had really bad joint and back pain. I have been researching this and found a lot of people have the same problem being on the levo. I want to switch back to the natur-throid as soon as it is available again. I never had all this back pain it is like I wake up and it last all day after I take my medicine.
