What do you think this is?

So I’m currently sitting here waiting for my doctor to phone so I can do a phone consultation with him due to some chest pains I’ve been experiencing for the past day. While I wait i figured just for the heck of it I’d get everyone’s input on here. So yesterday while I was running my chest started to hurt. It was more so my upper chest like right below the neck, and the pain increased when I took a deep breath. Last night after dinner the pain got worse, it hurt when I took a deep breath, when I leaned forward, when I lifted my infant daughter, when I lifted anything or used any upper body strength. Well this morning I woke up with extreme dizziness, I still feel dizzy now and the pain is still there. The pain is not only in my upper chest but also my shoulders, neck, and upper back. I can’t tell if this is heart related or it I pulled a muscle in my chest. The night before all this my workout consisted up all upper body movements, o do recall a pulling sensation in my chest when doing planks, sit ups, and weight lifting. I’m also constantly lugging my 10 month old around and when I have to bend over to pick something up while carrying her it does work my muscles for sure. I’m praying that it’s a muscle strain and I’m going to be okay but I’m still scared it’s something more. The dizziness just doesn’t seem right.

Has anyone else experienced any of this and been okay? Waiting for my doctor to call feels like forever. Ugh.
