I went through a very traumatic experience earlier this year, due to COVID my eye surgeries were delayed by a few months which cause me to go temporarily blind, and during this time it was extremely difficult. I have my sight back now. 

Now, I have this weird unexplainable shock that runs throughout my upper body, neck, etc.. It only happens when I think something bad happens, will happen, or a sudden loud noise. My body just completely goes into shock for 2 seconds and goes away afterward. 

For example, a man at Walmart came out of nowhere and said sorry for almost bumping into me and I froze. In that moment all of 4 seconds of interacting, I had a shock and suddenly was hard to breathe for a bit. 

Ex; when my bf does dishes and clanks them loudly, to him its nothing but to me I get shocks and I get scared/startled. 

ex; When I think something will fall if a bottle is so close to falling it's almost as if my body is preparing for it and I get those shocks again as if it did?? 

Going through what I've gone through, I'm trying to find therapy for it and alongside that, I've been experiencing these shocks a lot more and I hope someone can shed some light on what this might be?

Edit: just had another one right when I was about to post this, I moved my glass with my arm by accident but got another shock thinking it was going to fall..
