Pain near chest. A cardiologist?

Hello doctor, I am 30year old female. I got left hand pain before two months. After two weeks i started to feel light pains in left upper shoulder front side, then later statted to have shooting pains / uneasiness left chest area now and then. Sometimes ifeel back shoulder pain, lower back pain too, but they come when i dont have pain near chest too. Chest pain usualy lasts few minutes 2-3minutes, but uneasiness sometimes stays mostly until i take rest. I work as software engineer, dont have drinking smoking habits, my cholesrrol was 150. Hldl 40, vldl 100. Have no history of heart problems, bp. When ipick weight, iget sharp pains left or right side, and itgoes away when i put weight down. I have tested bp and sugar, they r normal. did 2decho its normal and tmt was negative. According to GP, she says my nerves weak and these are muscle pains. But theydont goaway. Should iconsult a cardioLogist? Because wheni dolittle extra work, ihave these pains and uneasiness.
