Heulwen, your TSH is good now but FT4 is still low because it lags behind TSH. This should improve when you've been on Levothyroxine a little longer but have another thyroid blood test in 6/8 weeks in case your Levothyroxine needs increasing.

Pins and needles may be experienced because your FT4 is low but I would discuss the pins and needles with your GP as neuropathy can be experienced when B12 is <500. GP may want to run further tests and to rule out pernicious anaemia as a cause of B12 deficiency.

Aches and pains may also be due to low FT4 but can also be a symptom of vitamin D deficiency which is common in hypothyroid patients. Ask your GP to test vitamin D.

Ferritin is optimal at 70-90 in women and 130-150 in men so it's unlikely you are iron deficient.
