Not responsive to my needs for specialists....I am a heart patient and take blood presure med. I have varicose veins bad in both legs with no reflux , swelling, and so painful that I get hardly no sleep at night....I have ask him to refer me to a specialist and he has told me in time...also I had to argue with his staff to get a Hep C blood test because my husband has stage 4 Hepatitis  C and it took 2 phones calls for this blood work order after I hate to get nasty because My husbands specialists said I had to have it...I feel I should not have to get ugly to get the medical attention I need.
