Last night I had made 3 lbs of CS Pecan Pie and a couple of minutes later after I put my fragrance oil in the wax my throat started to burn. My throat and nose was bothering me all night I woke this morning not being able to smell anything and still a soar throat. Is this normal when making candles? And if anybody can help me, what can I do to prevent this from happening to me. Thank you for any info that you may provide
