I'm 31 years female. I have hypothyroidism since few years and I take thyroxine sodium 25 mg. I have bad constipation from last month and recently started experiencing mild pain in my tailbone from last 2 days. I had tested my thyroid functioning and my t4 is 2 points more than normal range. My doctor suggested me to continue the same dose and for my constipation i'm taking cremaffin plus. But I don't take it regularly. I take it only when the constipation is bad. I'm afraid if it is an early sign of piles or anything serious. Please guide me.
