Over the past couple of weeks, I have been experiencing shortness of breath. I have not been tested for COVID-19 or know anyone who has tested positive, but I believe there is a strong chance that this may be the cause. Can Dr. David provide me with some advice on whether this is a serious condition?

I am 23 and experiencing erection issues in my relationship. There have been five occurrences in a month where I couldn't get or maintain an erection. I have not used any medication and have not seen a doctor about this. Sometimes an erection is achieved before sex but is lost right before the activity. I have not tried masturbating recently, and this relationship has been ongoing for a little over two months. What could be causing this and what should I do?

My sister is 27 weeks pregnant with twins, her first pregnancy, and she has a high-risk pregnancy. About 4 weeks ago, she tested positive for COVID-19, but she is healthy now and no longer showing symptoms. Her high-risk pregnancy specialist won't see her unless she gets a negative COVID-19 test, and I've heard that after having COVID-19, you won't test negative for 3 months. What should she do?
