I take BP meds. Valsartin and coreg. I am 78 years old and have had two open heart surgeries-2009 and 2015- both aorta valve replacements. Now having low BP and very tired and very sore joints. Just lowered Valsartin from 160 to 80 on Friday. This started May 9 after playing softball. Same thing Thursday and Friday after softball. BP still low this morning 108/58. Last week it was down to 88/46 and that is when they reduced the Valsartin. Guess that's it Thanks Patrick ( Pat ) Henretty
