Hello welcome to HCM. I have read your question throughly and I understand about your concerns. Your blood pressure around 170/100mmhg is high but in a long standing hypertension this fluctuations are known to occur. Your doctor needs to adjust medicines for sure but at present there is no need to be panic and rush to doctor if you don t have any symptoms. My advice to you is- 1. Take your morning BP medicines early around 7-8 O clock because in morning blood pressure will be highest. You can take it with tea only. 2.Make a BP chart for 15 days and then go to your doctor with that. 2 times a day checking is enough. 3. Eat more green leafy vegetables, daily 40 minutes brisk walking will allow you to control your BP. 4.Do your blood test like FBS, PP2BS, lipid profile and CBC every 6 monthly.
