Ganglion cyst

A benign growth from a joint, usually shows up on the wrist. While not dangerous this can be an uncomfortable condition. Rarely, they can cause numbness in the fingers, as well.

Gastritis and Peptic Ulcer Disease

Gastritis and Peptic Ulcer Disease are both problems with the lining of the stomach that can cause upper abdominal pain. Gastritis is the term for inflammation of the stomach lining that is commonly caused by a certain type of bacteria called H. Pylori. Regular use pain relievers called NSAIDs or alcohol can also contribute to gastritis. Left untreated, Gastritis can cause an erosion of the stomach lining and this is called Peptic Ulcer Disease (PUD). PUD is more dangerous because ulcers can cause bleeding into the stomach, perforate the stomach, and can increase your risk of stomach cancer. For most people, however, gastritis isn't serious and improves quickly with treatment.

Gastrocnemius Strain (Pulled Calf Muscle)

A muscle strain is a tearing or over-stretching of a muscle. When this happens in the calf it is called a gastrocnemius muscle strain. This typical occurs during a sudden forceful contraction of the calf muscle; like jumping, sprinting or playing tennis. This condition is often referred to as "tennis leg". When a strain occurs muscle fibers tear from being over stretched. Sprinting from a standing position causes the muscles to contract with a lot of force and if they become too taught they can tear. When this occurs it becomes very painful to use the muscle. There might be swelling of the muscle and possibly bruising. If there is significant bleeding a hematoma may form. Gastrocnemius muscle strain usually happens in individuals between the ages of 40-60 ('weekend warriors'). People feel a 'pop' in the back of the leg and often believe they were struck with an object. There usually is swelling and difficulty walking. The pain worsens by attempting to walk on heels or tip-toes. This condition will resolve on its own with proper rest, use of ice, and anti-inflammatory medications. After 3 days of rest most people begin to feel much improved. Individuals may begin light activity once they are completely pain free.


Gastroenteritis is an inflammation of your stomach and intestines which can cause abdominal pain, cramps, diarrhea, and vomiting. It is usually caused by an infection (usually a virus) or toxins related to food poisoning. Dehydration may occur as a result of profuse vomiting and diarrhea. Gastroenteritis is sometimes called a stomach flu, stomach bug, or stomach virus.

Generalized Paresthesias (Numbness)

If one is experiencing numbness all over the body, then an evaluation with a physician is necessary. Although generalized numbness can have benign (not serious) causes like hyperventilation or anxiety, it is important to rule out autoimmune disorders (Multiple Sclerosis) or diffuse neuropathy. Other causes of tingling throughout out the body are hypervitaminosis (high doses of vitamins) or viral infections (HIV).

Genital Herpes

Genital herpes is a sexually transmitted disease (STD) caused by the herpes simplex virus (HSV). Typically, the HSV-type 2 virus affects the genital area and the HSV-type 1 virus causes oral lesions (like fever blisters or cold sores). Type 1 can also cause genital lesions following oral-genital contact with a person with an active blister. The HSV virus cannot be removed from the body once infected but remains dormant within the nerve cells, and can reappear on the skin at any time.

Genital Warts (Hpv, Human Papilloma Virus)

Genital warts are caused by the Human Papilloma Virus (HPV). This virus is very contagious and is transmitted through direct sexual contact with an infected individual. The HPV virus is the most common sexually transmitted disease and infection with the HPV greatly increases a women's chance of acquiring cervical cancer.
