transient ischemic attack
"I've been taking this medicine for a little over 6 months.
I am a 66 yr. old female.  In 2014, I lost 30 pds. on purpose, so I have been feeling good, except age-related pain in my hip joints.
I've just realized recently that I'm no longer feeling pain in my joints. Nothing has changed in my life except the addition of this medicine.

So...I've concluded this is a POSITIVE side effect from taking this medicine."
