This does not sound like tendinitis.
A pinched nerve can present like this but should have shown up on EMG study.
ALS can start with variable symptoms but the course ofals involves gradual progressive deterioration and if you have improved it is unlikely to be ALS. MS again has a very variable presentation.
You need to have yourself examined by a Neurologist who can synthesise the clinical information with findings of an EMG test which may need to be repeated because it is an operator dependent investigation.
A pinched nerve should have shown up on EMG in wrist and forearm.
More extensive EMG would be needed for ALS or MS diagnosis.
