I have not been feeling myself lately, no energy to excerise, waking up with head aches pain on the right side and back of my head, irritable, frustrated easily, my hair is starting to shedding, losing weight and my appetite is not great. I have been diagnose with a thyroid issue about three years ago. I am on medication for this synthroid to be exact. Any suggestions as to what is going on and by the way I am 49 years old.
