Thank you for your response. I have gained 5 to 7 kgs of weight within 1.5 months. My face looks swollen, at all times one of my muscles are strained. I constantly have muscular pain. Have missed my periods (I have PCOS as well).
How can I identify optimal level of thyroid?
Since this is a thyroid disorders community, we'll start there. You said your thyroid hormone levels are within the normal ranges, so I guess the next thing to determine is whether or not, they're "optimal" - there's a difference between normal and optimal because we all have a certain place at which we feel best.
So let's start by having you tell us whether you have any symptoms of being hypo, such as the usual weight gain, constipation, fatigue, hair loss, muscle aches/pains, facial swelling/puffiness or others that you might be familiar with.
Also, if you have copies of recent thyroid labs (your doctor should be ordering Free T4, Free T3 and TSH on a regular basis), please post those results for us and be sure to include reference ranges, which vary from lab to lab so have to come from your own reports.
It would also be good to know if you've been tested for Vitamin B-12, Vitamin D and ferritin. All of these are necessary for proper metabolism of thyroid hormones "and" Vitamin B-12 deficiency can cause easy bruising. Folate deficiency and B-12 deficiency often go hand in hand and one can cover up the other.
That should be enough to start with and could be a good share of your problem.
