The thyroid gland is a small butterfly-shaped gland in the neck, just in front of the windpipe (trachea). One of its main functions is to produce hormones that help regulate the body's metabolism (the process that turns food into energy). These hormones are called triiodothyronine (T3) and thyroxine (T4). Many of the body's functions slow down when the thyroid doesn't produce enough of these hormones.
Esophageal spasm is a disorder of the rhythmic waves of muscular contractions (peristalsis) of the esophagus. The cause of this disorder is not known. Symptoms include chest pain and difficulty swallowing.
Esophageal spasms + anal spasms. I never associated the esophageal throat spasms or anal spasms that I have very infrequently with this condition. But evidently both can be symptoms of Crohns. Wow, are they ever painful! Kind of feels like a muscle cramp [Charley-Horse] in the calf of a leg only in my throat or rectum. Intense. but doesn't last long.
