I have a daughter who had a craniotomy for a colloid cyst in her brain two years ago, and since then has had health problems like weight gain, swelling, constipation, sore legs, fatigue etc. We think it is tertiary hypothyroidism, and the endos are putting her on thyroxine. Has anyone else had similar problems and have they any suggestions? Her TSH is .89, T4 11.5. No one seems to have much confidence in sorting it out . Does anyone know of a consultant who they could recommend?
