I’m a CNA with awful back pain. Should I continue my degree?

I’ve been working as a CNA in a fast paced hospital for 3 years and have 18 months left of my Bachelors degree to become an RN. For the last month I’ve had unbearable lower back pain. I think it started when rolling an incredibly obese patient for pressure care. Now it’s constant always and flares when I lift anything. I’m about to see a physio, but I’m so over this. Every time I work I’m in agony. I know there’s stuff like case management and doctors surgeries but I still have months of practicals to get through before I can even consider that. I’m wondering whether I should cut my losses now and find something else.
