Asthma and smoking weed?

I smoked a joint with 3 others the other day so probably took at the most 10 hits. i hadn't smoked in months prior to that and after smoking i'm not feeling 100%. i have asthma so that's a contribution but i went to the doctor and they couldn't find anything wrong with me, my blood pressure was fine, heart rate, oxygen level, everything seemed fine. should i be concerned? she said i just irritated my lungs so it would take a few days to get back to normal but now i'm having pains in my leg, just like a dull ache every once and a while. could that be unrelated and just me over thinking?
