I have facet joint arthritis. I have not been to dr in 2 years. No problems until June. I picked up several 5 gallon bukets of paint. I felt tightness in lower back. By the next day pain was running down my leg. I went to dr he said I had lumbar strain. After 2 weeks of treatment he sent me for mri. The results showed I aggravated facet joints. My work has assigned a nurse case manager . I am still paying dr bills. Can workers comp turn this down due to pre-existing condition? Should I contact a lawyer? I have not worked in 3 weeks. Thanks for any help.
