Talk to Psychologist on Fear Or Phobia

I feel nauseated after seeing blood, needle or even imagining my self in any sort of surgery, I want to know are there any pills for fixing this forever? Note that I never fainted due to this condition it’s just that it feels strange or unusual.

It happens whenever I imagine myself in any medical treatment like a few days ago I was searching and watching a video about Lasik Laser Eye treatment for myself it felt really strange my whole body was behaving differently I was feeling a sort of burden on my chest and throat plus breathing was difficult too so I stopped the video and within a minute everything was back to normal but when I played that video again all of it started happening again within 10 seconds and again stopped when I stopped watching that video.

Please tell me what is it and how it is fixed?
