Hi I'm rather new here but I'll start by adding I'm 21 and have had hypothyroidism back when I was 17. Took the synthroid, I believe is how you spell it, for a year before I turned 18 and lost my coverage at the free care then went till I was 20 without thyroid meds. Then got the ball rolling again after I just felt so sluggish and depressed randomly went back to free care, couldn't afford insurance, and saw the doctor. He started me back out at 50 mcg and I thought it was odd because I was already at 100 before I stopped taking it. So I said screw that after the first test came back saying my thyroid levels still wasn't good enough. Them I took 200 mcg after he prescribed 100. At first, it was good. My levels where normal and I was feeling fine for a change. Then, after about a month into it I started having these anxiety attacks. Small and short just light headed scared moments for no reason, which was odd because I keep my cool. I didn't think anything of it and just kept on. It wasn't till last week of Monday that I had a major panic attack followed by extreme fatigue and chest pains. I was so scared I was at work working a night shift as a guard and couldn't leave and it was 3 hours before my shift was over and all I could do was cry. I ended up leaving early and tried to calm down. My mom was worried about me and made me go with her to Huston because I was just so scared and in pain and had no idea what was happening. While in Huston, I ended up going to the er the first day tusday, because it was just to much and I kept having random anxiety and panic attacks and just felt awful. It was a feeling I hope to never feel again and hope no one ever has to. While at the er they didn't check my thyroid but in the blood tests it showed there was a blood clot. The doctor said it might have been a mistake in the test but they wanted to make sure and did the ct scans and such with the ivs and all that good stuff and came back okay. No blood clots nothing. Ekg was fine he rolled it up to a panic attack and told me to try and stay calm and such. Didn't help much and ended up with a $4000 er bill. So fast forward Saturday when I ended up back in the Er same problems but it didn't get worse or better. And I couldn't handle it much longer. I told them to check my thyroid levels everything I couldn't handle this another day. That's when I found out my thyroid levels where so high they went low like .1 or something I don't remember the number off the top of my head. He asked how much my thyroid meds mcg was I told him and he told me to cut back to 100 right away. No blood clots no anything just my thyroid was out of wack. It was weird because it completely screwed up everything about me. My feelings and I couldn't eat because I just felt worse after eating and eveeything. I got a follow up Friday but I am wondering if this happen to anyone else? I know it's my fault for being stupid and thinking I know my stuff, thats a $4000 lesson I'll never forget. The feeling is somewhat gone. I still feel... off but I feel 1000 times better than before. Just so worn out and my chest is sore along with my back along with being weak it feels like I had a stomach virus for 3 weeks. Can't eat a lot of solids yet because my stomach still isn't use to it. But I do feel everything returning to normal, very slowly. If something like this ever happened to someone else and if they know how long this will last before I feel back to my old self? I still feel the anxiety every now and again and my heart still races randomly but it isnt as extreme as before or anything. But i think my acid reflux is pretty bad now idk.
