beta mercap symptoms

Hey everyone, yesterday I was explaining to my PI how I can’t smell beta mercap, and he grabbed a bottle that allegedly had had some spill down the side and smelled quite strongly of it. He got me to smell it and I couldn’t smell it, but it has got me a bit worried if I’ve been exposed now. Before u went into the lab yesterday, I had developed a sore throat and some congestion, so I guess I was getting sick. A while after this incident with my PI, I started getting a migraine, stiff neck, and felt really sick. I’m like 99% sure this was related to whatever sickness I had and not the beta-mercap, but I’ve woke up this morning feeling heaps better, with only a sore throat and some congestion. Any chance I was exposed? And that caused these symptoms? What are the symptoms of exposure anyway? I didn’t smell it, or have any irritation/burning in my nose. The migraine and other symptoms didn’t start until maybe an hour or two after this.
