My mother in law is having heat flashes. All her blood work is normal including diabetes, hormones and thyroid. She doesn't have any b food allergies. The situation is so bad that she can't even go out and can't tolerate any heat. Her body reacts very bad and there are always hot and red patches on her face. We went to all dermatologist and primary care physicians but nothing has worked for her. She avoids sea food and chicken to prevent it from getting worse. It's not rosacea or lupus. She is very stressed as no doctor has been able to diagnose what is actually wrong. What should we do and which specialist we should reach out? Last time her area around eyes had bumps and was very red.
