Not able to name the problem. Pls.

Dear sir, My wife is suffering few helath problems. Actually we really worried about the issues  as we don't know the problem is. Few days before my wife had complain that she has some difficulty in breathing and pain at chest.The same thing occured before few months also but it was cured automatically by the time. We went to doctor recently and undergone all medical tests including blood,CKMB, Chest X ray and ECG. All the reports are normal. But that day doctor has given injections diclofenac 50 mg and pantop 40 mg. But since that day she started to say more discomfort and pain at left hand part, numbness, and little pain at chest. More pain is at left hand side at around the neck and left hand. It is like pain starting at neck and travelling to left hand. Severe pain at left shoulder. We are really worried  as we don't know what the problem is even all reports are normal. She is taking too much tension for the issue. Pls tell us actual problem and whoom shall we consult. pls...
