Question: I notice some mild discomfort in my upper left chest, more noticeable if I press on it,

the discomfort is sharper if I press in the middle of my upper left breast; at some times the discomfort is more noticeable than at other times (variable), more often with with movement or without movement when I lay on my left side.

if this is being caused by inflammation and I prefer not to use painkillers, other than warm compresses, are there other natural methods to reduce inflammation I could try? is it likely to resolve on its own?

On a related subject, is there a test to determine the extent of plaque build up in the coronary arteries, under what conditions/symptoms would it be advisable to be tested, and what test would you recommend to determine the extent of the build up (if any).

I have two questions on different subjects:

1. When I was younger I used to sweat easily even with a relatively modest amount of exertion. This has changed noticeably, for example, this morning it was admittably a cool day (65 degrees), and after a slow jog for nearly an hour, I barely sweated. Also noticeable is less underarm odor, I can often wear the same T-shirt two or three days without any odor problems. Should I be concerned and what could some possible causes be?

2. I suffer from a some form of erectile dysfunction for about a year now, I can get hard enough to penetrate about 1/2 to 2/3 of the time, however, I can only rarely stay hard enough to make it to ejaculation. My wife can usually bring me to ejaculation with the mouth and then vibrator after I become soft. Although staying hard and achieving ejaculation the normal way would be vastly preferable, the above has apparently become our new normal. I do not feel that I suffer from performance anxiety and my wife is very supportive and understanding. I focus on her satisfaction before penetration and we seem to be ok in the sex department despite the above setbacks. On rare occasions I am unable to achieve ejaculation. Could this be an indication of arteries to penis not so clear as they once were, or possibly a hormone problem? I have never smoked, am 6 feet tall and weighed 161 pounds this morning, have really tried to pursue a healthy diet (organic, no processed, cut way down on sugar and dairy, pursue regular exercise, eliminated unhealthy fats, cut way down on fried foods, try to eat more vegetables, have tried to eliminate GMOs, take a variety of supplements, etc.). I do have the problem of waking in the night for a pee run (oddly always seems to happen about 2am) and then having trouble going back to sleep. I usually can go back to sleep but it can be one or two hours later, can't stop the wheels in my mind turning it seems. Being retired, I make up for any lost sleep with an afternoon nap. Is this just a sign of getting older and there is nothing that can be done about it? (Note: I don't want to take any prescription drugs because I am afraid of the short and long term side effects and don't believe they address the underlying problem(s) anyway.) What could you recommend, if anything, and your thoughts ... anything I could try to improve the situation?
