Muscle pain and burning but no weakness? Normal emg and ncv twice this year. Normal petct brain. Normal bloods cpi aldolase. What could this be?

Probably not serious. Small fiber neuropathies can cause burning pain with a normal ncs/emg but the odds of this are pretty rare for a 25yo. When does this occur? With exercise? Maybe you are deconditioned. Anxiety can also play a part . If you are on klonopin, (clonazepam) does it help the symptoms? If you have no weakness and labs are also normal i would be more reassured.
