Localized infection anywhere in the body can produce tenderness to touch, pain, and warmth. Examples include abscesses and cellulitis. Traumatic injuries can also produce similar symptoms. Seek the advice of your doctor if you have been injured or if you believe you have signs of an infection anywhere in the body so that you can receive appropriate treatment.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
Hydronephrosis describes swelling of the kidney resulting from the inability of urine to drain from the kidney into the bladder. This may be a normal variant or it may be due to an underlying illness or medical condition. Symptoms of acute hydronephrosis may include: intense flank or back pain radiating to the groin, nausea, vomiting, bloody urine, sweating, and colicky pain, which may cause the person to writhe or roll around or pace in pain.
Kidney stones are solid masses of crystalline material that form in the kidneys. Symptoms and signs of kidney stones can include pain, nausea, vomiting, and even fever and chills. Kidney stones are diagnosed via CT scans and specialized X-rays. Treatment of kidney stones involves drinking lots of fluids and taking over-the-counter pain medications to medical intervention including prescription medications, lithotripsy, and sometimes even surgery.
Cellulitis is an acute spreading bacterial infection below the surface of the skin characterized by redness, warmth, inflammation, and pain. The most common cause of cellulitis is the bacteria staph (Staphylococcus aureus).
