Can somebody recommend a doctor/endo who can help with thyroid and HRT?

Hi,

I need somebody who has knowledge of the thyroid, especially very low TSH and low FT3, also need help with my HRT. Currently on 75/100mcg of Levo daily. GP reduced from 100mcg 3months ago. On 2 pumps of oestrogel, experimenting with 2 one day and 3 the other day. However, not sure if this is the right dose. Have very dry skin, terrible hair loss, now knee and ankle pain. Want to switch to Estradot. GP not comfortable with switching, I'm frustrated with the delay. Also, take Utrogestan and Vagirux. Thanks.
