Talk to Internal Medicine on Headache

Hi everyone recently, I did TFTs, Cortisol, Prolactin, Testesterone, CBC, ALT, Ultrasound of nick and thyroid, FSH, LH and Lipid Profile. While all above tests were done between 8am and 10am. all tests are normal except Serum Prolactin =20.10 ng/dl, Serum t3= 0.95 nmol/L, Serum t4= 4.38 ug/dl, TSH= 1.860 uIU/ml, Lipid Profile as HDL= 19, Triglycerides= 984, Cholesterol = 208.

kindly guide me any endocrinologist what shoud I do. I feel pressure in my head and sometime headache. I rarely feel frequent need of urination.
