<s>[INST] I m 25 weeks pregnant and I m having strange sensations in my head, when I blink my eyes wobble and feeling like I have extra fluid in my head. I m currently decreasing my tablets duloxitine 20mg every other day, amatriptaline to 10mg a day & oxycontin to 20mg a day. I m not sure what would be causing these symptoms the pregnancy or reducing of my tablets. [/INST] Hi, thank you for providing the brief history of you. As certain symptoms arise due to medication and contacting the gynecologist for the same should help change the medication. In some cases few medicines do not get adjusted to the physiological of certain individuals and change of medication can help a lot further. Also, during pregnancy there is a high physiological process occurring for the development of the child. This head wobbling can be due to less oxygen reaching the brain and performing Lamaze's exercises will help you to ease the physiological health and also improve the delivery process.
