Hi hollie26 the more experienced people on here will probably ask if you have been diagnosed wirh a thyroid problem and if so they will need your blood results and lab ranges to help you. If not you could ask your doctor fir bloods to be done if you are concerned, i am hyperthyroid with hashimotos diseaase and i do have symptons similar to yours breatlessness, swollen neck etc, being hot and heartbpalps. But you could be hypo instead. Hang on in there for other people to respond.x
