I am 54 and haven t had a period in about 7 or 8 months. Strange symptoms... Have been losing adhesion in my nail beds. My nails are become thin and brittle too. Starts at the outside edges and works its way inward and progresses up to the top of my nail bed (closer to the knuckle) I ve also noticed my skin is dryer and I get tiny dry patches on my upper arms and shoulder... Not a lot and they come and go. Final symptom is that I ve had painful nodules surface along my neck. They re no bigger than half the diameter of a dime, but they hurt. They go away in like 2 to 4 days, but come up in other areas on my neck. Right now I have two. I think this may be thyroid related, but I am not sure. Any ideas as to what it might be? I am height-weight proportionate, but have gained about 15 lbs over the last 3 or so years. I am height-weight proportionate and don t take any medications b/c I have always been very healthy.
