I get really achey cold feet, they throb and are freezing cold (I take nifedipine for the coldness), at night my elbows lock whilst im asleep but soom wakes me with excruitating pain I scream when trying to bend or straighten them, my finger joints are always hurting too, my knees, shoulders but not hips. MY QUESTION IS AM I RIGHT IN THINKING THAT LUPUS DOES THIS OR IS IT SOME OTHER KIND OF ARTHRITIS??? Please share your thoughts. Thank you xxxx PS HAVE HAD 4 BLOOD TESTS ANA EQUIVOCAL??
