Can a thyroid test that showed a normal FT3 and TSH but an extremely high FT4 be correct?

Hello doctor,

I am 29 years old, 57.87 inches tall, and weigh 97 pounds (lb). I have had an allergy since last year. I initially visited a private physician. He prescribed Claricort, Prednisone 20, and Cefuroxime 500 mg for a total of 10 days during my initial checkup. He was also given a prescription for Prednisone 10 mg for 10 days, along with some Calamine (Caladryl) cream to use if the itching persisted. I went to a dermatologist since even after taking all those medications, my allergy persisted. I was told not to consume things like chicken, eggs, and other things. And she prescribed me Levocetirizine 5 mg tablet for 20 days and apply Triamcinolone lotion to my allergies. Upon return check-up, she prescribed another medicine called Montelukast 10 mg tab for 30 days and use Triamcinolone lotion and Aveeno derma. During my third check-up, she additionally prescribed Montelukast 10 mg for 100 days. Sad to say, I stopped taking Montelukast sometime due to fear that too much intake of this medicine might cause a lot of adverse reactions in myself and in my body. So, I do not know if this is why the reason my allergy did not vanish. There was a free medical check-up in our province with doctors coming from various parts of the world. I tried to see one, and that doctor prescribed me to take Cetirizine with Montelukast, Prednisone, and Albendazole and she requested for a Thyroid Panel, CBC, Urinalysis, and SGPT. If I could do all those tests, she advised me to see an endocrinologist and an allergist. However, due to some circumstances, I was not able to do all those tests. In another medical check-up that was done in our province, our health officer advised me to do a thyroid panel and an ECG. Yesterday, I successfully had my thyroid panel and, the result was a normal FT3 and TSH but, a very high FT4. I went to a hospital and, she said that the result is normal. Is she right? Kindly help.

Hello doctor,

Thank you for the reply.

I failed to mention that I occasionally have trouble breathing. I, therefore, will not be able to deal with the sun's heat from sunrise to sunset. My neck itches a lot. Kindly help.
