I am a 52 year old female. I have trivial mitral regurgitation, a pfo with small aneurysm (in the heart), asthma, restrictive lung disease, numerous allergies (food and environmental), possible ulcerative colitis. I feel cold all the time, and sometimes my temperature feels okay and then all of a sudden I start feeling like its dropping. Could this be from my poor health? The "feeling cold" problem has been there since childhood, but seems worse now at this age.
