Hello and thank you for asking!
Sorry to learn about your bothersome situation.
Of course it may be an insufficient levothyroxine
dose causing the above mentioned symptoms, but the only way to verify it, is to check the thyroid
hormones, at least TSH level
If it elevated, the levothyroxine dose should be raised.
There is very dangerous to increase the dose without a biochemical confirmation.
Will be a pleasure to suggest you further how to raise the dose after the TSH result.
Hope the information will help.
