Left leg and Left arm unresponsive.

I woke up with my left arm and left leg being heavier than my right for atleast 5 mins at 3am in the morning. Its been 5 days since. I could move my limbs but they were extremely stone heavy than right. No tingling or numbness just heavy. I was horrified. I have had a Brain MRI 3 years ago due to anxiety symptoms. It was normal back then. I have had strange symptoms like palm sized pressure in the left side top of my head which happened atleast 7 times last year and then completely stopped. The last pressure episode happened at nov 2025 when I woke up in the morning and suddenly had palm size pressure in the same area with my left index finger and left thumb tingling. It never happened since. However 5 days I had my left leg and arm feeling like it was being pulled stronger by gravity when I woke up randomly at 3am. I am only 22. I have been taking bisoprolol 2.5mg for 3 years due to severe anxiety. That medicine keeps my bp at 104/73, HR at 73 on rest. So far, it's always after sleep.
