Looking after little ones can be challenging and demanding, but yelling at your son won't induce sleep for him.
Pain in the chest could be from anxiety, but if it continues it would be wise to seek medical help.

I had chest pain just like that yesterday that wouldn't go away all day. I finally went to the After Hours clinic, and they did an EKG on me, took my blood pressure, listened to my heart beat. My heart was fine. It turned out to just be my anxiety (which was high that day) and tense muscles. They gave me an ibuprofin shot and it went away. To say the least, I felt really dumb. It's probably anxiety. When I told them I thought it was my heart, they said they doubted it because of my age (22). Try to take your mind off it because concentrating on it will only make it worse, and try taking advil or ibuprofin.

My chest pain, which I thought was due to my anxiety, turned out to be acid reflux. I had absolutely no symptoms of heartburn or anything, but apparently you can have acid reflux or gerd and only feel the chest pain. I thought it was my heart, too. When it got really bad, the pain would radiate all over my chest, my back, and my shoulders. Anxiety can definately make acid reflux worse, and in my case, my anxiety provoked a bout of it. I would check in to that. Hope you feel better. I know the stress associated with raising little ones. I have a 2 year old and a 3 year old, and sometimes I want to rip my hair out. Just take a couple of minutes, breathe, and try to stay as calm as possible. I have to tell myself "this is a temporary situation... why get so upset over it if it's not going to last forever?"

I tend to get the same thing with my anxiety/panick attacks. I had that problem two weeks ago but it turned out mine was from a sinus infection and bronchitis.

It is probably your anxiety. If it last for a long time then you know , you should call a doctor. But if you relax and it goes away, then it is just anxiety. Tell yourself if this is a heart attack I have nothing to worry about. It will be over. I know watching shildren when you are exhausted is so frustrating. Focus on relaxing togther and enjoying the moment. If you just focus on "gotta get him to sleep" you are just going to get frustrated. I know it is easier said than done, but I am in the same boat. And when I just give in and enjoy the rocking the baby to sleep , I feel much more relaxed.

it can be a sign of anxiety.. i suffered from chest pain when i'd get stressed dealing with my teenage son -- im now on medication and it helps alot.. the chest pains lasted for hours and it was unbearable along with trouble breathing..

I have never had chest pain from anxiety, so I don't really know if it could be something to worry about or not. But I do know that a heaviness in the chest can be a sign of a heart attack, especially if you are over 40. It probably isn't something that I would take any chances with. It probably is nothing, but you never know. I hope everything is okay with you. And I have kids too, so I know how you feel. Getting them to go to sleep can be rough!
