Hi, I've been on levothyroxine since July, the smallest dosage. I'm also taking 20 mg of fluoxetine. The past few years I've been very tired (which I contribute somewhat to the fluoxetine and is normal), and my memory seems to be declining (way before I started taking the fluoxetine). I am only 22 years old, so I'm HOPING it is due to the hypothyroidism. My question is if this is a possibility or not? I have trouble concentrating, but I'm pretty sure it's not ADD or ADHD. I can get things done if I need to, but it takes so much out of me to be able to concentrate and actually remember things. I used to remember EVERYTHING, now I can't remember something as simple as where I put something earlier in the day. I've been under a lot of stress these last few years as well. I've also been experiencing neck pain more so than usual. I have about eighteen nodules in my throat. I had them all checked, so far they are not cancerous. I feel like they are growing though and maybe new ones as well lower in my neck as well as around my chin area. I think I am very sensitive to caffeine, the only thing I ever have with it is coffee. It's hard for me not to drink any, but when I do my throat does feel a little better. I've asked others about this, but they never noticed a connection. I go back to my endocrinologist sometime this month, and I had my blood retaken. So I will be asking him as well. But I just figured I'd ask some people who have gone through this as well. Thanks for any help.
