Pain from shoulder to finger.

My wife is having pain, sometimes - from left shoulder to elbow or to fingers, sometimes in left chest (she feels burning on a point), sometimes the pain start in right side or in abdomen, she is feeling this random pain from 9-10 days. Her ECG reports were mild changes,Lipid report were elevated and the echo reports were normal. The doctor prescribed the medicine below : 1.Tab. Methodac-M once daily after breakfast 2Cap. Calciva- Gold once daily after breakfast,lunch or dinner. Cap. Roseday-A 20 once daily after dinner. And ask her to walk for atleast 30 min. But its almost 10 days, she didn't get relief from pain, (pain is not that much,but regular), only will feel better and low pain after taking medicine. And also BP is also sometimes high even while sleeping (like 130/98), or sometimes normal (may be due to medication) Please suggest what sould we do or any test recommended.
