What would cause bleeding gums, intermittent tachycardia, bruising and over all feeling of not feeling well? I've read posts after posts and so far my doctor has not found anything! I'm under the care of a hematologist who has not seen anything remotely like leukemia, anemia, or difficulty with white or red blood cells. The white blood cells were low at one reading and ok the next. I was hospitalized for tachycardia and nausea a month ago, but nothing like that since. The dentist said that my gums were bleeding excessively but with no sign of plaque or gum disease. All other panels show normal thyroid function, with normal levels. The cardiologist ran tests and all is well with my heart. Still waiting for results of tests for RA, fibromyalgia (sp) HIV and lupus. I have shortness of breath after exercising or during it and daily doses of sweating and intermittent night sweats but I thought it was all menopausal in nature before I had bruising and all these other weird symptoms. Included in this is anxiety attacks as well but they are also the menopausal symptoms I've had before, just more frequent.
