I'm wondering what can cause the following symptoms:
hair loss, joint pain, cold hands and feet, headaches, tiredness, excessive sweating, nervousness, mood swings.
I'm a 21 year old female within normal weight and have experienced the above symptoms regularly.
I agree with Wink. it sounds like a thyroid problem. I'm hypothyroid and take medicine for it. I had all the symptoms you've listed except for excessive sweating. once I was diagnosed and prescribed medicine, I started feeling better after taking the very first pill.
