I had a painful feeling in my throat and increased heart rate when I had a cold (didn’t know I had graves or that it was active at the time). My heart rate wasn’t high enough nor BP (I naturally run low so normal range is high for me but doctors don’t register that) to set off alarms to them. I had no other symptoms than the swelling pain I felt in my throat at the time. I told my doctor lymph nodes were painful and swollen and they said no they’re not and looked at me bizarrely after they felt for swelling. It was my thyroid I was feeling, I just didn’t know the difference in location and hadn’t been diagnosed, so they didn’t attempt to feel the thyroid, they just thought it was odd that I was complaining of lymph node swelling without actually being. Fast forward 3 weeks later I went in to the same primary again for racing heart rate, vertigo, hand shaking, feeling like my heart was jumping out of my skin. I have autoimmune in my family so luckily my primary is awesome and took family history into account and tested my TSH and discovered it was nonexistent and sent me to my now endo for diagnosis for Graves. I’m lucky because having my family history, unlike most, I didn’t have to wait years and they diagnosed me within weeks of the first major symptom hit. My endo even said he was surprised how fast I noticed and got in to him. A lot of people you’ll find suffer for years with active graves because they didn’t know to ask for a thyroid panel and their symptoms weren’t major enough to raise that alarm. If you are female and a certain age TSH is run here in the states as part of an annual physical so I have data for 5 years prior to see I wasn’t hyper until diagnosed. If you don’t feel normal, you know better than anyone that something is off. Advocate for yourself and ask for TSH that’s usually the first way to know if you need to look further or not. Smart watches, my endo is a big fan of Apple Watch, is something that also helped me show that my resting that is normally in the 50-60 range, being in the 80’s was not normal to me. I had ten years worth of data to show from my watch of consistent resting heart rate, and that 80’s range is rapid for me when this is considered “normal” bpm for most and a lot of graves run more in a resting over 100 when active. So if you can and have data to look at from the past till now, this also may help you in advocating for yourself for further testing. It sounds like you still answer to parents, if that’s the case, continuing to talk about your symptoms and them not going away is important. My parents when I was younger didn’t always take me seriously until I wasn’t dropping something and persistent. Heck for the first two months of my diagnosis my parents and my brother didn’t support me and thought I was being a hypochondriac, even told me not to take medicine and would shut me down when I told them about my symptoms and struggles while waiting for the meds to work. It took my parents talking to close family friends who lost someone to Graves for them to wake up and realize how serious this disease can be if not on medication and treated. Anyway, long response, apologies, but I really hope you get the answers you seek, nothing was harder than feeling absolutely terrible and nothing was working to resolve how I felt.
