Can CRPS be the cause of high blood pressure? Never had a problem before- CRPS in foot following fx, surgery. Dr a bit concerned.

YES. CRPS is a dysfunction of the sympathetic nervous system, and as such can be involved with multiple organs. One example is the kidney, which does play a role in blood pressure regulation. In end-stage CRPS, the intractable hypertension changes to orthostatic hypotension. If your doctor is concerned , maybe you should consult a specialist in hypertension management.
