How Are Charley Horses Diagnosed?
If you occasionally have a charley horse, you do not need to get a diagnosis from a specialist. In contrast, if you frequently have recurring spasms (more than once a week without a known cause), you should seek medical treatment.
Charley horses are diagnosed by means of a complete review of your medical history and physical exam by your specialist. During your exam, your physician will look for and assess any tight or hard muscles that you may have that are tender to the touch.
If your specialist suspects that your spasms are the result of nerve damage, an MRI may be ordered to get a detailed diagnostic view of your internal structure. Your doctor may also recommend that blood tests be taken to identify if there are additional health conditions causing cramping.
