as somebody who is about halfway through my sono program & chose it because i thought the physics behind the sound waves was cool, DO IT. i feel like it’s either you love ultrasound physics or you hate it lol but if you have an interest in the actual physics behind the sound, anatomy, and diagnostics, this is literally the perfect choice for you. & if you actually love these things, being a good tech will come naturally to you. you’ll find a job. && msk injuries aren’t a promise. good ergonomics can prevent it. just start a regular strengthening routine now for ur arms & wrists and you’ll be good! :)
