Blood Pressure - taking medicine AMTAS - AT (INDIAN MEDICINE) CONTAINS- Amlodipine Beeliate BP

                              equivlant to Apilodipine 5mg and Atenolol 50 mg.

LISINOPRIL - 10 MG Tablet - Taking 1 in the morning. Sarted last 2 years along with Metformin.

I never have such problem before. It started last week.  My problem is going for urine more than normal durations and feeling slight burning.

Symtums:

When i am busy or doing work then i go to urine may be after 3-4 hrs. When i am free then feel some thing like burning and go after 2 - 3 hrs. But to night was very incomfurtable feeling, not pain but something unusal and little burning. Burning is mild (bearable), and when i pass urine it susides (over) for some time. During Night time once i passed urine with gap but other times is ok.
