Trouble finding the right job

So im currently unemployed since i previously worked a hard labor job that grew to cause me too much endo pain. Im trying to find work as it is difficult to live on my fiances income alone. Does anyone gave any recommendations for jobs i should look for or jobs youd recommend? I have pains just fron doing things around my small apart ment and running errands so its tough to find a job i can handle with the pain. Or if anyone has tips on how to reduce pain easily while working? Any advice and help is so very much appreciated! Thanks in advance.
