Hello, I am a 27 year old female with no serious health conditions that I m aware of. For the 4th or 5th time on Friday evening, I woke up burning up and sweating excessively. When I stood up, I immediately felt extremely dizzy and light headed, and my chest hurt very, very badly and breathing seemed to make it worse. I was extremely hot, so I got an icepack and laid back down, and after about 20 minutes, I started to feel better. I felt fine prior to this - went to dinner, and had a normal evening and nothing was abnormal. With the exception of one time, this has only ever happened to me before as I am sleeping, and I m always woken up because I am sweating so profusely and my chest hurts so badly. Today, the symptoms aren t nearly as acute, and I m no longer excessively sweating or hot, but I still feel off. Shortness of breath, and mild chest pain.
