Calf muscle

I recently noticed my left calf muscle on inner leg to be much smaller and with three dents in the muscle when flexing. Doctor refered me to ortho doctor but was hoping someone had a similar situation that they could shed light on what is going on. I have slight tingling in the leg every once in a while and it twitches constantly at night. Instead of a smooth muscle on inner calf it has three dents.

Thanks in advance

Hi there.  Calf dents could be normal or due to muscle atrophy and loss of muscle mass. Muscle twitching is due to stress, exercise, dehydration, insufficient calcium intake, mineral imbalance like magnesium, potassium, due to no specific cause, ALS and MS. Appropriate tests must be conducted to exclude the possibility of other conditions like EMG and certain findings can support the diagnosis of ALS. NCV results may suggest whether the patient has a form of peripheral neuropathy or myopathy rather than ALS.MRI can be checked for other problems like spinal cord tumor, a herniated disc in the neck, syringomyelia, or cervical spondylosis, infections range from HIV, HTLV 1, and lyme disease, multiple sclerosis, etc may all be considered. Consult a neurologist for detailed evaluation. Take care.
