I have been diagnosed with high bp recently and taking medicines. How many days does it take for bp levels to come down? It was 190/100 2 weeks back and then started taking medicines. Since then I went to check bp, once it was 150/90 and another time 170/90. I keep having random pains in left neck shoulder and find it difficult to sleep. I have shown to cardiologst who did ecg and echo and said it is normal. Cholesterol normal but vitamin d and b12 deficiency and taking supplements. Also high blood sugar detected taking medicine. One doctor told medicine effect could cause pain and discomfort and that it can take many weeks for bp to stabilize, is this right sir? Please advise
