what causes calves to swell
The calf is swollen and tender. To rule this out alone I would see your primary doctor. Other causes are more rare. A Baker's cyst is a common condition in which part of the joint behind the knee forms a growth. This is normally not concerning, but if it ruptures it can cause a swollen and tender calf. If this is the case, pain medicine can be given until it heals. Other causes could be from muscle inflammation--a myositis. There are many types of myositis which can be from many causes. Simple muscle inflammation from overuse is another cause--in fact the most likely. Fluid overload--from heart problem or kidney problem or liver problems can also cause swollen calves. Again these are more likely in older patients--it is possible and must be ruled out. I would see your doctor to rule out a few concerning causes of swollen calf.
