back pains and having hard time breathing.

Yesterday the back pain was terrible. The whole day today I am feeling something is pressing on my chest. I hope its nothing serious. I hope it will be gone by tomorrow. I hope its just spasm. Now there's still some pain on my left back side and when it hurts it goes all the way to the front. Shocks I'm going nuts with this.  Maybe I should stop drinking coffee. I am getting palpitations, I am not used of drinking coffee thats why.
