I was very tired, dry skin, hair fell out, fingers tingled, short of breath
Well there can be many symptoms with low thyroid.
Feeling cold, slow pulse, low body temperature, dry skin, constipation, hair loss and thinning , depression and mood swings, tiredness, brain fog, frequent infections, and the list goes on.
The thyroid controls the metabolism, and all systems can be sluggish due to thyroid insufficiency.
Hope this helps, but you could soon check with a full thyroid blood panel, being FT3, FT4, TSH.
Good luck
