Wait, why not 112 mcg? Going up 25 mcg daily is a lot. Even going up 12 mcg daily can be too much. I change my dose by one pill a week when I change, but I am very sensitive. Most people who have been treated for a while, meaning you are not recently diagnosed, do not do well when they raise their dose daily, they wind up over medicated.
Meanwhile, it has happened to me more than once that a doctor said I should go up when I should be lowering my dose. Well, a nurse called with the result and new recommendation, but I assume it was from the doctor. What is your TSH?
I had a friend who had appendix pain off and on for a few years. She went to the doctor a couple times for it, emergency a couple times. They always said it was not her appendix. Finally while on a business trip she wound up in the ER again and they did an appendectomy, and it was indeed inflammed. After that she never had the pain again, so she was right all along.
Is there any chance your fever is a flu coming on? If you have a seemingly idiopathic fever, I think that is pretty significant if you also have right lower quadrant pain.
How about eat some raisins or prunes and drink a glass of water, and hopefully you will have a bowel movement and feel better.
