I started OP about 3 mos ago. Love that my teeth were becoming not sensitive to hot or cold anymore. Then about a month ago I started having the same reaction. Got horribly sick for a couple weeks, started having a sore throat w/blisters and swollen glands. (I rarely ever get sick) I went to the Doctors and they didn't know what the blisters were and told me to just stop OP. So I did thinking I was having an allergic reaction maybe. Now me teeth are becoming very sensitive again so I decided to start OP again (I use EV Coconut Oil) and right away I am starting to get the sore throat w/blisters again! Rawfoodgirl - did this ever go away for you? I'm debating if I should continue or maybe just try a different oil?
