Smooth muscle spasms: A muscle spasm is the sudden involuntary contractions of the muscle which can be painful and uncomfortable. When the nerve impulses that control the muscle movements are damaged or interrupted, it could lead to muscle spasms. Symptoms include muscle tightness, joint stiffness, unusual posture, difficulty in moving, and pain in affected muscles and joints.
Circulatory problems: The circulatory system is responsible for sending blood, oxygen and nutrients to various body parts. When blood flow to any specific body part is reduced, it could lead to poor circulation. Symptoms include numbness, tingling sensation, pain, muscle cramps, and throbbing or stinging pain in limbs.
Peripheral vascular disease: It is a blood circulation disorder that causes the blood vessels outside the brain and heart to narrow and block. The narrowed blood vessels cause reduced blood flow. It could occur due to the deposition of fat and calcium on the walls of the arteries. Symptoms include pain in the leg, especially while walking.
Erectile dysfunction: It is the inability to keep a hard and erect penis suitable for sexual intercourse. It could be a sign of physical or psychological conditions such as fear of sexual failure, anxiety, depression, low self-esteem, or stress. Certain health-related factors such as smoking, drinking, being overweight, being physically inactive, and having high blood pressure also contribute to erectile dysfunction. Symptoms include difficulty in getting an erection, decreased sexual desire, and difficulty in maintaining the erection during intercourse.
