Hi, I was wondering if you could help me. I wake up every morning feeling great. At about 11.00 am to noon my vision gets blurry and heavy. Its been going on for about a week now and I was hoping you can tell me something. Also I have had sever chest pains for yrs now. I went into the ER one time to check it out because I was getting scared. The run a whole bunch of test on me, with respect to EKG and all the other stuff but it turns out I was fine, nothing abnormal with this chest pain all i have to do to sooth it of get rid of it is pop it like you would crack your knuckles.
