benign prostatic hyperplasia
"The urine flow improved slightly but the worst thing that occurred was my heart racing & blood pressure rise after having a hot shower at bedtime. Usually my BP is around 120 / 80 pulse 55 .When this occurs it was 158/103 pulse 146, also I get a fluttering sensation in my heartbeat which is irregular.
This does not happen every night but It has only occurred since taking tamsulosin for the last 2 months also feeling tired & lethargic."
