I recently had a complete physical. I am 54 years old... everything checked out great. expect my white blood count was alarming low. I am going in for more blood work in a week. I have not been sick with sore throat or flu like symptoms but I have not felt right for about 3 months. I had thyroid surgery 2 years ago. removed my left lobe but I still have my right side... my levels were great. I am a runner, work out about 4 times a week, play golf, tennis etc. very active . I am a healthy eater . I am having leg crapps, night sweats, chills, still have periods. should I be concerned or is this normal.... thank you.
