AMA with medical doctor going on now! Have a question for the doc? Please post it here!

So the good doctor who did our last AMA was happy to do another one for us, so if you have a medical question that you are reluctant to ask your own doctor, feel free to post it here, and the doc will do his best to answer it. The doc is a legit medical doctor who has been verified. Please keep in mind that the doc is doing this in his spare time, and will answer your question as soon as he can, so please be patient. Please keep casual discussion off this thread please, so it makes it easier for the doc to see questions and answer them. And dont be an asshole and troll the doc or you'll be banned from the sub. It's hard as hell to find professionals willing to help with harm reduction and contribute to this sub, so let's not run them off be being complete jack asses. Thanks u/StimsAMA for taking the time to out of your schedule to do this, its much appreciated!
