Question: Hi doctor (cardiologist), I have been troubled by unwanted erections during my sleep for more than a year now. I am quite sure it happened after I started using a man's oil, and it is a lot more than normal nocturnal erections. However, that is not my question now. Most of the time I stand out of bed to let the erections subside, since this is the fastest way to do it, then continue to sleep, then up again a few times every night. However, lately I have felt some discomfort in the chest when I do it. Sometimes I don't get out of bed, but stand on my knees in the bed instead and let the erection subside that way. Lately, after such event, the next morning I would feel warmth in my left hand (the smallest finger and the part connecting to it) and some warmth/muscle ache all the way on the left side of my chest, almost near the arm pit. Also some discomfort in my chest throughout the day. I would like to know if repeatedly standing up with erections during the night has a damaging effect to the heart, and should I avoid it? Sometimes I turn on the light and read instead, but then it takes longer time before erection is gone. I am not overweight, but feel stressed because of back problems and also some health anxiety, which makes it hard sometimes to differentiate real symptoms from "fake" symptoms, which feel real, but maybe something like a nervous heart. I would appreciate some advice for me, and if there is any possible danger? I don't believe I have any blockage in my coronary arteries or such kind at my age (family history, weight etc).

Thank you for fast reply. I have stopped using that oil now, but without any help. It is advertised online as "Man 1 man oil". I only used it occasionally, but I believe it triggered these strong erections during the night, as it fits the time it started and I have no other explanation for it.
It is not every time I stand up with erection that I feel something in my chest, but more than once now to want me to clarify it further, and it seems like standing on my knees is the worst (with erection), because twice now the last week I did that, and the following morning I have felt some warmth in hand and discomfort in the chest. So it is interesting to hear you say there is more blood in internal organs which may explain it. And likely, the erection has been present for a while before I wake up and notice it. It disturbs my sleep a lot.
I will not provoke it any further, will try to let the erections subside without getting up. I didn't find any information online about erection and its affect on the heart, so I wanted to make sure I wasn't doing any great harm.

Forgot to let you know about other medicines: I have been using Rhinocort (nosespray) every day for almost 10 years because of nasal polyps, and I also use Aerobec daily, because of bronchial asthma. Other than that, occasionally ibuprofen/paracetamol.
