My husband who is 54 years old stated he was working and in a stressful situation, he started having a pain in the middle of his left chest muscle. The pain went away within a few minutes but this caused him great concern. The pain was not like pressure where he could not breathe, it just hurt he said. He recently had gall bladder surgery and when we were discussing his sweating at night and how it soaks the bed the surgeon said that we should have his heart checked out. That was about a month ago, his surgery. He is under 200 lbs. he has lost some muscle tone what we thought was due to his gallbladder issues. Tonight he did eat before bed and now again the bed is wet from sweat, however the pain in his chest is gone and apparently only lasted a few minutes. He is very active and he is planning on running in a 1/2 marathon in a couple weeks. When we call for an appt. with our MD how soon should we get in? Today? Same week? Or later?
