I had a full thyroid test the t3 t4 they said it looked great.. I'm wondering if there's a way to check hormones.. I have an apt. W my doc. Aug. 6 th and was going to ask about that. Sometimes another thing I feel is that I swallowed a big pill and it's stuck in my throat.. It happen the past 2 days and it stayed there. Thankfully that part is gone but I'm still dealing with this constant lightheadedness and heart racing.. I'm out on disability from work because of it. I've had MRI, EEG, ct, chest X-rays, ton of blood work, echo/stress test. I am currently now wearing a heart monitor but every other test has come back great.. I know having a baby and breastfeeding can really screw with your hormones but idk what to do.. I don't want to stop breastfeeding I wanted to go to a year and my son is 9 months now.. But I'm beginning to think its the only thing I haven't tried.. Because this lightheadedness is keeping me from doing so much.. It's like all I can do is lay here all day. It's hard to take care of my 9 month old and my daughter who will be 5 next month. any suggestions from anyone would be great.
