Welcome to the forum, PawPaw.

225mcg is a very high dose to start on but has considerably reduced your TSH. 18.7 is still very high but it will take 6-8 weeks to fully respond to 225mcg and should continue decreasing. Most people will feel well when TSH is just above or below 1.0 but it will take some time for this to be achieved.

If you're having trouble swallowing the tablets you can crush them and mix them with water. The goitre may shrink a bit when you are optimally medicated.

Hypothyroidism can cause chest pain among other symptoms and this may improve as your TSH reduces.

It would be a good idea to ask your GP to test ferritin, vitamin D, B12 and folate which are commonly low/deficient in hypothyroid patients and can cause musculoskeletal pain, including chest pain, fatigue, and low mood.
