Complex Regional Pain Syndrome (CRPS) can have severe and debilitating effects. Its cause is unknown and its treatment problematic, usually a medication regiment. CRPS also present special problems and issues for claimants for disability insurance benefits as shown in the recent case, Holmstrom v. MetLife, No 09-2173 (7th Circuit, August 4, 2010). The case also illustrates the maneuvers that disability insurance benefits companies will undertake to avoid paying benefits on disability insurance claims.
