What causes intense headaches and pounding sensation in the chest?

Hello doctor,

I do not know where else to turn, and I am getting concerned about my health. Recently, I have been experiencing these intense headaches, and sometimes I feel this pounding sensation in my chest. I decided to check my blood pressure at home, and the readings have consistently been higher than what is considered normal. I do not check at the same time but still, they are always 130 or 135 by 90. I am really scared about what this might mean. I have heard about hypertension, but I do not want to self-diagnose. The thing is, I am not sure what steps to take next. Should I be worried about these symptoms, and if it is hypertension, what can I do to manage it? I do not want to neglect my health, but I am feeling a bit lost and anxious about the whole situation.

Kindly help.
