My Daughter has just come up with the same this morning, for blood pressure she is on.
Betaloc CR and Amldipine went to the DR and she told her to rub some cream on, to me cream is not going to do anything, tomorrow she is going back if it doesn't work, Dr did not know what it was, she is also on other meds for bipolar, and gets that creeping, crawling feeling in her legs at night.
