I seem to be having a hard time with this brand of test im taking. Me and my friend both had severe pain, redness, and swelling. His is gone after six days and mine is still there. I think I may be sensitive to high levels of BA. My other friend suggested putting a pin through the stopper, submersing in boiling water, and letting the BA or alcohol steam out through the pin. Any thoughts on this one. I cant spend 12 weeks limping around. Thanks.
