I was taking Lotrel 5/20 and had a bad ringing/roaring in my ears that drove me crazy at times. About four months ago I ran out of my pills and thought I could get by without them but my bp went up to 184/118. While I was off of them the ear noise seem to go away. Now that I'm back on them the noise is back. Could this be a side effect? Also my legs ache very bad.
