I have been having chest pain (sharp but not not extremely painfull) on the left side of my chest for 5 months now.  With this I have been getting lightheaded (dizzy) , the lightheadedness has been getting more and more frequent over the last 2 months.  It almost feels like something in my heart is clogged and then it releases and this rush of lightheaedness goes through my body.  I am 30 and I do smoke but since getting this I have cut back from approx 18 cigarettes a day to 6 a day or so.  My caffine intake is not a worry to my doctor.  I have had 4 children the youngest being just 1yrs olda week ago.  They have checked my heart all out, quite well and done a lung scan.  All normal.  I did have an upper GI and it came back I do have a moderate amount of acid reflux and started Perriet (I not sure about the spelling of that) which doesnt seem to be doing much.  I am so scared as the is a history of blood clots and heart attacks in my family (my mom has had 2 brain clots).  The chest pain is here almost all the time now (more then not).  Please help, Also the pain is not always on the left side but mostly, it has gone to the right, and down my left arm too.
Thanks for your question on Chat Doctor. I can understand your concern. First no need to worry about cardiac chest pain as your ECG is normal. HERD (gastroesophageal reflux disease) related symptoms is more likely because your upper GI (gastrointestinal) copy is suggestive of reflux disease. Smokers are more prone for reflux. HERD needs lifestyle modifications along with Chat Doctor.  So follow these steps for better symptomatic relief. 1. Quit smoking as soon as possible. 2. Avoid hot and spicy food.3. Avoid large meals, instead take frequent small meals.4. Go for walking after meals.5. Lose weight if you are obese.6. Avoid stress and tension, be relaxed and calm.7. Keep 2-3 pillows under head in bed.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
