How bad is your posture?
Symptoms of kyphosis, that may be present or not, depending on
the type and extent of the deformity, include mild back pain,
fatigue, appearance of round back and breathing difficulties.
Severe cases can cause great discomfort and even lead to death.
Treatment for kyphosis may involve anti-inflammatory drugs as
well as exercises to strengthen the abdominal and hamstring
muscles
Basically, if it is a mild case, it should be easily corrected
with correct workouts.
