I know that alleopathic doctors can be more than frustrating - but they teach what they are taught - prescribe a drug and/or operate. However, there is light at the end of the tunnel - some MD's are actually going more holistic. And even better - the public at large is starting to question their methods - the stats on people who seek "alternatives" is amazingly high percentage-wise.
But about your low body temp (mine is low too)....It may be related either to your thyroid or your adrenals - maybe your immune system needs some TLC. That's the route I'm going.
