Thanks for contacting with your health concern
1. going by the symptoms which you have provided it could be a possible problem with pituitary or thyroid gland [or both].
2. Check with a gynecologist [if female], or
Endocrinologist since initial problem with
low thyroid level could be there or even independent PCOS [polycystic ovarian syndrome] may be present as in both condition acne/facial hair, fatigue, is associated.
3. hormonal imbalance related to low thyroid can cause or aggravate joint pain/muscle cramping, so taking natural anti-inflammatory herbs like turmeric, ginger, garlic, vitamin C can ease arthritis pain
PS. As your age can't be deduced let me clarify that
Hormone imbalance does occur naturally, such as in puberty, menopause, and perimenopause or may also be caused by toxins or an unbalanced lifestyle, so check with your
primary care physician to exclude the same so that appropriate management can be started. [perhaps the most common medical treatment of hormonal imbalance is the prescription of bioidentical or synthetic hormones. This is known as
hormone replacement therapy, HRT]
