You would need to explore what your state's policy is on Medicaid/Medicare and Returning to Work after receiving SSDI. When I last looked at my state's program, it would actually save me about $500 a month in insurance expenses if I returned to work--a nice incentive.

You might also qualify for a government job that is less physically strenuous than your current job and might pay more. (I would call Ticket to Work at the very least before just assuming it would require training you'd be unhappy with.)
