Lowered body temp is a symptom of Lyme for sure!! Most people range from the 95.7 like you to running a slight fever at 99 degrees or slightly higher.
My body temp stayed at 97.5 for years and years before I finally had enough treatment to change it. The only time my temp would go down that low was when I got a cold or flu. When it finally hit 98.6 and stayed there for a whole week, I did a happy dance with my doc!! LOL!!!
PS - do be careful using the oven to warm yourself!!!
Keep up the drinking of hot teas (herbal) and maybe try an electric blanket to wrap around you instead???
