Levothyroxine side effects or something else?

Posted , 4 users are following.

Since 2016 I have been having heaviness on my chest, sometimes feels like a panic attach other times I feel like I just can't catch my breath, or bad heart burn. I have a pain from my jaw to my clavicle, restlessness in both arms and legs, pain in the kidney areas, ankles and feet swelling (more so now) and feeling anxious, I also have had heavy periods (sorry for the tmi). I had went to the doctor and he at first said it was possibly Fibromyalgia because I have been dealing with lost of stress and then ran a blood test and I was diagnosed with diabetes. He then focused just on my diabetes. I have had these symptoms off and on these past 3 years and until recently no one had checked my thyroid (been to 2 other doctors). Well I did a health fair and did a full panel and it showed I had an under active thyroid. So made an appointment and the doctor was still fixated on my diabetes. I had to bring up the thyroid and so he, although hesitant, prescribed me Levothyroxine along with changing my diabetic medication from just Metformin and Farxiga to Farxiga and Janumet (Januvia and Metformin mix) and stopped the single does of Metformin. Now two weeks later I feel like I have a 300 lb person sitting on my chest and cant even climb a flight of stairs without feeling I am going to pass out and my feet are more swollen then ever. I feel extremely anxious, i feel like I am not getting oxygen to the brain, having a weird pressure headache. I tested my blood pressure, pulse and oxygen and all show normal. My lipid panel shows within range of everything other then my glucose, iron and thyroid. I am so nervous. I emailed the doctor today because of what I read of the side effects of the thyroid med, I have some of those side effects listed but he says he don't think so. I am at a loss here. Can anyone else relate?

    PS, I am on the lowest dosage on all the meds. Just in case that was an inquiry.

    do you have any results for your thyroid levels, before and after starting levothyroxine.

    When I was first diagnosed I was kept on a low dose for a long while and felt much worse. Levels should be checked 6 to 8 weeks after starting the tablets and increased if necessary.

    Post your results so more advice can be offered.

    Also low iron can cause lots awful symptoms.

    Regards Elaine.

    My thyroid was reading at 6.5. I have not done any other tests at this time to determine anything other then me showing hypothyroid. As of today, I am no longer on Levothyroxine because of the side effects. My heart is showing normal on an EKG. So I am to check in this Friday after being off the meds for 2 weeks to let the doctor know if I am having the same side effects.

    levothyroxine did not work for me, my doctors encouraged me to keep increasing doses for 2 years before they finally switched me to armour. Armour made a HuGe difference. My panic attacks were gone, i was less fatigued, but it takes time to notice changes. good luck!
