Inner thigh cramps can be caused by straining or overusing a muscle; deficiencies of dietary minerals such as calcium; insufficient blood circulation in the muscles; and dehydration, according to MedlinePlus. Extended periods of intense exercise and physical labor can cause muscle cramps throughout the body, notes Mayo Clinic
Muscle cramps are generally harmless and usually go away on their own without any medical intervention, but they can be painful and temporarily disable the affected muscle, according to Mayo Clinic.
Inner thigh cramps frequently occur at night or after physical exercise and can last up to several minutes, according to MedlinePlus. Health conditions such as a pinched nerve in the back or neck or a spinal cord injury can cause nerves to malfunction, resulting in debilitating muscle cramps. Symptoms of muscle cramps range from a mild spasm to excruciating pain. The muscle may feel hard to touch or appear distorted beneath the skin.
Muscle cramps can be managed by stopping the activity that induced the cramp and gently massaging and stretching the affected muscle until the cramps stop, according to MedlinePlus. If the muscle cramps persist, it is important to see a doctor for a thorough medical examination and appropriate treatment.
