Just like any other job being a physical therapist can be a stressful job at times but it's not as stressful as being a surgeon or other doctor in the emergency room who's on the go all the time and sometimes have to work a lot of overtime when emergencies arrive to the hospital a lot in just one night.
Being a physical therapist is a less stressful job when it comes to being a doctor since you're not on call as much like other doctors, nurses or surgeons.
A physical therapist job is a pretty good paying job as well at $50,000.00 to $100,000.00 per year depending on where you're located and where you work at.
