The thyroid gland is hugely important because it is the only means by which your body absorbs iodine to produce a hormone which is necessary for nearly every metabolic function in the body (everything from body temperature regulation and brain development, to converting food into energy).
Sprainâcomplete or incomplete tear in supporting ligaments surrounding a joint caused by a twisting or wrenching motion. Strainâacute or chronic injury to a muscle or tendinous attachment caused by stress, overuse, or over stretching. Classified as mild, moderate, or severe (see Classifying sprains and strains)
How Is a Strain Different From a Sprain? Even though both can hurt a lot, strains are not as serious as sprains. Because a strain is pain in the muscle, it may start to hurt immediately or several hours later. The area will be tender, feel sore, there may be some swelling, and it might also appear bruised. A sprain will probably start to hurt right away.
