hi..Thanks for your query.
Symptoms you mention are consistent with the diagnosis of Rosacea
made by your dermatologist
.The common triggering factors of rosacea are excessively warm environments,Beverages : Alcohol, especially red wine& beer,hot drinks,emotional influences,physical exertion,Stress
What you are experiencing are a result of exposure to the triggering factors.While there is no cure for rosacea and the cause is unknown, medical therapies are available and steps may also be taken by individuals to effectively control or reverse its outcomes. I would advise you to take care and avoid the above triggers.Medical management may be require on and off basis.
Hope this helps..Take care!
