Doctor referrals, cardiologist, & other stuff

OK, so I go into get a yearly health checkup, basically a blood test.

For the most part everything checks out decent.

Blood pressure a tad high(117/83), LDL cholesterol a little too high(117), Serum Creatinine(.70) a little low and Testosterone low(312).

My NP suggests I take a testosterone shot every now & then to boost my energy levels back up. I have been feeling a lil sluggish.
What say the OT Dr's, nutritionalists, RNs...?
Are T-shots legit? What else?

Now I would like to get a good check-up on the ole heart, stuff like an EKG, stress test, maybe an echo cardiograph. Heart conditions do run in my family so I want to check this out.

I call my doctors office about this and they say I need come to them to do a 'referral' to see a cardiologist, so I have to take time out my busy schedule and come seem them just to have them 'refer' me to cardiologist.

To me this seems like a waste of time, effort AND my money.

Can't I just schedule a cardiologist and skip my primary doctor? Who is a good cardiologist in the Monroe/West Monroe area?

BTW, a little background, I am 5'10", 220 lbs(over weight and need to drop about 25 lbs), middle 40s, white male. I used to a gym rat but I have stopped going to the gym all-together, I do a little physical activity but not much. I eat an above average diet,nutritionally speaking.

I have BlueCross/BlueShield insurance.

Sorry if TL or Germans...
