To the Doctors:
I have just been diagnosed with a
benignBenign ear cyst or tumor
Benign positional vertigo muscle cyst in my right thigh. I am very interested in understanding what would cause such a cyst. I have been a jogger and race walker for the last 15 years, and for the last year I have done
dailyDaily combo
Daily multiple for men 50+
Daily multiple for women
Daily multiple for women 50+
Daily multiple vitamins
Daily vite
Daily-vite men's formula
Daily-vite weight control calisthenics and stretching exercises.
My questions are the following:
1. How
commonCommon cold are muscle cysts?
2. What is believed to cause them and could they arise as a result of exercise that may injure muscle tissue over time?
Muscle cysts are quite rare , so rare that I have been unable to find a
quote incidence in the literature.
The underlying causes are varied, frequently a cause is not established
but in some cases the development of a cyst is related to
acuteAcute bilateral obstructive uropathy
Acute bronchitis
Acute cerebellar ataxia
Acute cholecystitis (gallstones)
Acute cytomegalovirus (cmv) infection
Acute gouty arthritis
Acute hiv infection
Acute kidney failure
Acute lymphocytic leukemia (all)
Acute lymphocytic leukemia - photomicrograph
Acute pancreatitis trauma or
damage to a muscle.
This includes compartment syndrome in which muscle degenerates due to
compromised blood supply, leakage of fluid from the
kneeAnterior cruciate ligament (acl) injury
Anterior knee pain
Bursa of the knee
Dermatitis, herpetiformis on the knee
Knee arthroscopy
Knee arthroscopy - series
Knee joint replacement
Knee joint replacement prosthesis
Knee pain
Kneecap dislocation
Meniscus tears joint into muscle,
and parasitic infection.
Muscle cysts have not been linked to physical activity such as you describe,
given the large numbers of people who exercise regularly we would expect
to see muscle cysts much more commonly if this were the case.
