Hi Jamesy,
Thanks for writing your query.
After reading your post, it seems that your symptoms are due to increased blood pressure.
You should monitor your blood pressure twice daily for atleast 3 consequtive days.
There might be a possibility that either the dose of your medicine has to be increased or the medicine has to changed.
Your symptoms will get cured if your blood pressure is controlled.
You should get following investigations done :-
1. ECG.
2. Renal profile.
3.
Lipid profile.
4. Urine examiantion.
5. Head scan.
Also avoid eating salty and oil rich foods.
I hope this is helpful to you.
Thanks.
