I had a series of blood work done and all came back normal except my HDL is low. I have an appt already for a artery doppler. my left hand just above my rings have started to turn purple and the skin on the top of the hand is scaly and doesnt feel like real skin .. the dr thinks that i may have a blockage somewhere. what should i do?
Hello, The purplish skin discoloration of skin on your hand can result from arterial insufficiency.  For this your doctor has referred you for upper limb arterial Doppler.  In this the areas and flow of blood will be investigated. Medicines will be prescribed according to your condition. Hope this helps.
