I just got my last blood work results regarding my thyroid. This time I did not require med adjustement. Yet, I still feel very tired. I cannot get through my day without having to nap it out. If I go about my normal chores, it draines the life out of me. Shopping seems to be very hard, a trip to the grocer and back and I need to rest it out with an hour or more nap time. In the past I have been anemic, they removed my uterus to regulate that in 2004, last april I underwent major surgery, I had a clementine size tumor in my colon, fortunately I did not need any chemo since it was not at an advanced stage. My last biopsy was last march which turned out good. Why am I having so much trouble getting my full energy back.
