RN who had two craniotomies

I am 29 years old RN, have been working for 3 years in Rehab hospital when I had to take a medical leave due to CSF leakage. I have been on medical leave for 8 months now because I underwent two craniotomies this year without any complications. I am still recuperating and my doctor gave me a medical clearance to go back to work in first week of january. My boss was very nice to offer me a part time 16 hours job night shift in neuro rehab floor which is different from the floor i used to work. I know that working in rehab floor requires alot of heavy lifting and boosting patient. Although my surgeon gave me no restrictions with my job I still feel worried about my health. I have been trying to find another job that is less stressful and doesnt involve too much lifting but its very hard to find one. I had interview with Fresenius last week part time outpatient in the clinic and had verbal offer that I got the job and training will start in February. I also applied for school nurse job but I didnt hear from the school yet. My question is how stressful working in dialysis? I am scheduled to go back to work in January in Neuro Rehab floor and would like to see how can I handle working in the floor again. Do you think working in dialysis clinic is less stressful than working in Rehab floor? Thank you everyone
