Hey. Thanks for writing to HCM.
To answer your question no eye drops cant cause any of these symptoms. Those drops are just to keep the conjunctiva
or eyes wet for the normal functioning. Its purely coincidental that the symptoms began when she used the drops. For her symptoms does she have any pain in the neck radiating to arms or legs? Keep her posture straight and give her pregab M along with vitamin D3
Hope this helps. Take care
