My daughter, age 35, has seen a physician several times. She is a landscaper and frequently has to leave work early because she starts throwing up, gets nauseous, and sometimes dizzy. She takes her temp, digitally, and it is normal . Is there such a thing as a sun allergy? Her doctor just can t seem to figure this out. We thought heat stroke but doctor says NO. This use to happen periodically butnow Otis much,ore often.
