sick due to lower back pain and stress

I am 57 years old and I have a few disabilities namely diabetes, asthma, lower back pain which leads to a trapped nerve and ulcerative colitis.  I am currently on the sick due to lower back pain and stress.  I have had s meeting with work who have sent me to an occupation health consultant who I have just been to see and he encouraged me to go back to work in the next few weeks and has done a report saying the same.  I don't particularly want to return to this job and I wondered would i
be able to claim any benefits i.e.  I already receive PIP but wondered if I could also claim EDA as well.
