My mothers foot big toe hurts - there are foot vessel occlusion - big toe pain hurts so bad i can not sleep - doctors said the report 'dorsalis pedis'?

Big toe pain: She may have peripheral arterial disease especially if the dorsalis pedis pulse is missing. See a vascular surgeon for help.

See below: If they are showing an occlusion of the dorsalis pedis blood vessel then they should recommend treatment or referral to a vascular doctor for surgery or treatment for embolic disease. The pain is due probably due to lack of blood flow.
