When my hands are by my side they go red/slightly purple. They go normal color if raised, happens in hot or cold, (not raynauds?) pulses fine? Thanks

Vascualr surgery. The symptoms described above seem to be do to an anatomic problem. It may be do to one of the vascular form of thoracic outlet syndrome or another related condition compressing or compromising blood vessels. Consultation with a vascualr or cardiothoracic surgeon is recommended.
