Hypothyroidism is a clinical disease. What it means is that lab tests only serve to guide the clinical diagnosis, they are not a diagnosis by themselves. The exact abnormalities you have in T4 & TSH thus could help in the diagnosis IF an MD suspects Hypothyroidism. As for the problems you have, they can be caused by many things like diet, low vitality, stress, depression, various hormonal upsets including hypothyroidism, testicular infections, etc. Hence you need a proper clinical diagnosis based on physical exmination and then a correlation with lab tests. Wrongly taking thyroid medication on a suspicion of disease, just based on lab tests, can be quite harmful.
