Numbness in left arm and chest tightness

I have been going through high bp 150/90 and anxiety episodes from past 2 months. I fee like pins and needles around my chest area. I have gone through several ecg and all came out to be normal except sinus tachycardia. My 2d echo is also normal and ct coronory angio suggests calcium score nil and left dominance with no significant narrowing in coronaries. My crp level is 2.05 mg/l. I am taking sartel beta 25 for my high bp and now it is in the range of 130/84. I want to ask what is the reason for this numbness in my left arm and slight chest tightness. Once in a while i feel thumping in chest that wakes me up from the sleep and i feel scary. Please help me out. Investigations Ecg: normal 2d echo normal with lvef 61% Ct coronary angio normal Haemoglobin: 12 Lipid profile: normal range
