Muscle stiffness can be caused by a lot different things. It is a very common problem. It can be caused by neurological disorders, lack of available energy, lack of excercise, excess body fat, excess inflammation, medications, and poor nutrition.
When our muscles don't come in work they do not burn lipids to produce energy.So our body can't burn lipids to produce energy .so we feel our body not functioning very good due to less energy .This malfunction of our voluntary muscles is known as stiffness.
Stiff person syndrome (SPS) is an extremely rare progressive neurological disorder characterized by persistent rigidity and spasms of certain voluntary muscles, especially those of legs and feet.
The flexor muscle in my left elbow is stiff.
Rigor mortis... is the action of the body's joints seizing up after death has occurred. Tetanus... is an infection in living tissue caused by a bacteria. Both involve the muscles and their joints but in different ways. Rigor mortis is the reason why the word "stiff" is a slang term for a dead body. Two or three hours after a person or animal dies, the muscles start to stiffen. This phenomenon progresses in a downward, head-to-toe direction. In 12 to 18 hours the body is, as the saying goes, stiff as a board. Tetanus, also known as lockjaw, is an infection characterized by muscle spasms. In the most common type, the spasms begin in the jaw and then progress to the rest of the body. These spasms usually last a few minutes each time and occur frequently for three to four weeks. Spasms may be so severe that bone fractures may occur.
Sounds as though it's muscle spasms, but that doesn't explain the dizziness. You could have two things going on at the same time...

The "sac" between a man's legs is called the scrotum. It is what protects and contains the testes. The scrotum also regulates the temperature of the testes. When they are hot, the skin becomes very soft, and there may even be sweating. When the testes are cold, the skin of the scrotum becomes stiff, shrunken, and leathery.
Chemical changes in the blood after death cause a dead body to become stiff within hours after death. This stiffness is called rigor mortis. It usually goes away within 12 hours of onset.
you will have to give the horse a lot of massages in the part of leg that is stiff and give the horse inflammatory tablets to and hopefully that should work x
