I am 39yrs. old. For the past three years I have experiencing a dramatic loss of fullness in the face. It is mainly in the area commonly known as the laugh lines. I am also noticing a tightness and pulling sensation in the same area. In the past 18 months I have been tested three times for HIV/AIDS; all have been returned with NEGATIVE results. And although I have not been specifically tested for hepatitis, all liver test have resulted in numbers well within the normal range. I am asking what else could be causing this problem? And is it possible to have hepatitis and still have normal liver function? I have not found a doctor who will order a hepatits test because they have said that it is not necessary due to the fact that I have normal liver function. Please help. I am ccurrently without health insurance, so doctor's visits are extremely difficult!
