Elevated ESR and high platelets count are characteristic for a condition that is very often misdiagnosed as Fibromyalgia, due to similar symptoms.
That could be happened with you, too.
It is called Polymyalgia Rheumatica, and is manifested as widespread muscle aching and stiffness, primarily in your neck, shoulders, upper arms, thighs and hips.
This is an inflammatory disease, that can disappear by itself after period of 2 years in average, and can be treated successfully in a meantime.
If your TSH level is higher than 5, you can be suspected for low thyroid functioning, or hypothyroidism.
The decreased metabolic activity associated with hypothyroidism usually leads to increased blood levels of cholesterol.
