What could cause my blood pressure has been jumping up and down I have a heart arrythima take 2 med for this. Having weird feelings last couple days?

Jumping bloodpressur. There could be several reason for your jumping BP and weird feeling 1)your heart could be out of rhythm 2)your heart could be beating too fast or too slow from time to time. 3) this could be also side effects of the medications.
Be seen. You need to see your cardiologist. Your heart may be becoming harder to control its rhythm with medications.
