WARNING
This is not An ACUTE symptom:
Its really not adviced to self prescribe in these "complex cases" specially not from a discussion forum.
Lets say the patient gets an aggravation from this remedy suggested on line,who will help the patient,who will follow up in the next following weeks/months? What happens if there is a suppression of symptoms,making the patient worse later on.What happens if the patient's vital force is not up to par/if he cannot sustain the suggested potency?
Again please do not Self prescribe!
see the directory I posted for a trained classical homeopath. Its for the best interest of the patient.

Running to the nearest drugstore and getting this remedy is NOT adviced. "There are a possibility of hundreds of remedies/potencies."
