<s>[INST] hey hii am having pain in my chest from past 5months....i get it checked(sonography and mamography) but nothing was there.But still i am having the pain.Some time its not there and sometime its there...he said i have used some machine while doing exercise.He said the pain is in the bone below the chest.It will go slowly.But i thought of using the multivitamin(supradyn).Is it fine? [/INST] Thanks for your question on Chat Doctor. In my opinion it seems muscular pain only. But in intermittent pain, we need to rule out cardiac cause first. So get done ECG first. If this is normal than no need to worry much for cardiac cause. And multivitamin will not cause any harm. I advise you to follow these steps along with multivitamin for better symptomatic relief in muscular pain. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Take good painkiller and muscle relaxant. 4. Apply warm water pad on affected site. </s>
