Having High Blood Pressure Problem. How To Get Cured?

Sir, I was having high blood pressure 140/100 max 1 year before then I asked by the Doctors to take Pinom 20 and Lipicure 10 mg once in a day for 2 months and then I came back to Haiti where there are no doctors availabe where I am posted . I continued for 2 month and then stopped to take . 5 -6 month my BP was normal all the time and then when I went to India i just went to see doctor for normal check up and they found that my BP was 140/100 ( may be due to Jet Lack reason bec North America and India s time difference are opposite ) and I was advised to continue with Telvas 40H and Lipicure 10 mg . when I came back to my place i.e Haiti my BP was always Low like 90/65 most of time . Then I called to doctor and he advised ,me take only telvas 40 without H but still it was low BP and when I called to same doctor to India he was not responding my phone . Then some of my relative told me to take Telvas 20mg..... Now I am taking Telvas 20mg and Lipicure 10. last month I took Lipid Profile where we found that no need to take LIpicure 10 mg and I stopped it. Now still my BP is low like 90-100 / 65-70. Then here in haiti , one doctor told me to split this Telvas 20 Mg and take half dose beacuse Telvas 20 mg is minimum dose available in the market. so I started to take half of Telvas 20 mg since 3 days and I didn t check my BP right now . But I am feeling some kind of movement at Right and Left side close to Kidney area, I really don t know the name so i mentioned near the kidney are. Please tell us is due to the half dose of Telvas 20 mg Medicine or it is normal .... This started from the same day when I started to take half dose of telvas 20 mg . I shall be very thankfull to you u help me bec here in Haiti i don t have anu other option .
