I am experiencing tingling in my left foot, leg, and palm of left hand especially at night. Just for a test, last night I took only 15 mg Actos and the tingling was nearly gone. I take my Actos just before bedtime. This morning my sugar was a little higher (119) than normal (85). So I took the other 15 mg Actos and guess what? My tingling is back. I think it is the Actos causing this problem.
