I had my hip replaced 3 1/2 weeks ago. I have always had cold hands and feet, but last week it has been worse. I get chills in the evening/night but only in my back area. No temp. BP normal, HR in 70 s. On BP, cholesterol, ASA, Synthroid (thyroid removed, just had levels checked), Wellbutrin medications. Occasional Celebrex and Tramadol. Incision not red. House is 71 degrees, but again feet and hands cold but do not get discolored. After a few hours I then get quite warm and need to remove extra blanket/jacket. Hands/feet somewhat warmer. I am 52 and active.
