Thyroid ups and downs can be very hard on a person because of how it will make you feel and most often that is very bad. If you are in the very horrible process of your thyroid failing or sometimes called thyroiditis then it is an awful thing to go through one day you may be sweating and nervous and the next you may be freezing cold.
When your thyroid is starting to attack itself most often through it’s own antibodies then that is how you thyroid will attack upon itself. When this attack is going on you may have both the horrible symptoms of hyperthyroid and hypothyroid and can go back forth quickly when is down right awful and very miserable.
You can go from being nervous and edgy with a heartbeat that is often very fast one day. The next day you may be so cold and tired that you may not even feel like getting out of bed at all. This is a very hard cycle to go through for any person that has to suffer through this.
The worst part of the whole thing is that this process of your thyroid failing could last from a couple of weeks to years even which can be very hard for you. You will not know how you are going to feel from one day to the next day because it can be different each day.
