I am a 39 year old woman who had a hysterectomy 13 1/2 years ago. I am fair skinned and have always burned rather easily. I however have found that in recent years i have increasingly become more sensitive to the summer heat. It use to make me feel like a wilted flower now it literally makes me sick for days after to much time in heat. Is this normal or something that I should be concerned about and seek more information from my doctor?
