My friend got CMV retinitis because her immune system tanked during chemo for leukemia--ALL. After the chemo was finished she still had problems with the eye and the ophthomologist gave her an injection of Kenalog right into the eye. A few weeks after that my friend started to gain weight, sometimes as much as 10 pounds a month. At the time of her injection her TSH was normal. Yesterday, 35 pounds heavier than she was 6 months ago, the TSH was > 100!!! Basically, she has no thyroid.
This is a very serious situation. Please be aware of possible side-effects before you have a Kenalog injection.
