It is completely normal for you to need a referral to see a specialist. There are a lot of people that are hypochondriac. If they could just go see a specialist every time they thought something was wrong with their heart, kidneys, liver, head, eyes, skin etc healthcare costs would be massive. A specialist in my country (in Europe) has an hourly rate about 4 times higher than a primary care doctor, so having a primary care doctor filter through the patients and hand out proper referrals when necessary actually saves money.
