I have a law blood pressure of 90/60. is there any danger that a damage might be caused to the peripheral heart nerves and should i take a medication?

If you are healthy: with a normal blood pressure of 90/60 & no symptoms- then I would not worry. However, if you are ill and this is a marked drop in your normal blood pressure - would discuss that further with your physician.

Many would envy you!: If this is where you BP normally lives, wonderful! If it is a sudden drop, you might feel it in the form of light-headedness or dizziness. Track your blood pressure over a period of time and see what you average. You can buy an easy-to-use home cuff for under $70 at your pharmacy or warehouse store. LGromko MD
