6 days ago i was priming some parts for paint using a 2 part epoxy primer, it took about 30 min. I smelled the paint through the respirator a couple times while painting but it went away after readjusting the mask. The next day i found a small tear in the rubber mask part and also developed a dry cough with mild difficulty breathing that same night which i have had since then. went to the doc today and they said it was a mild chemical irritaion in my lungs however no x-ray,sound right or should i get a second opinion?
