Amlodipine
"Started on 5mg once a day.  Withing three weeks had episode of eye pain and severe conjunctivitis.  I didn't suspect the med and neither did eye doc.  Medication (drops ordered for eye problems). Conjunctivitis became chronic despite meds. Severe fatigue.  Withing five months I was having pain and difficulty walking.  My BP responded well and was normal, but had increased difficulty on short walks, developed  "brain fog", stopped gardening, walking, daily exercises.  I did not connect the med with the symptoms until a year later when I was unable to walk three level blocks because of leg, back, and foot pain. I decided might be the med and stopped it.  Now perfectly normal and BP mildly elevated. No more BP meds for me."
