Anyway, from your description, I have reached a diagnosis. The picture should confirm it.
What you have is Herpes zoster or Shingles.
It is caused by the reactivation of Chicken pox virus which remains in a dormant stage within the nerve cells and come out along the skin supplied by a nerve branch. This is why it is one sided usually. It could cause severe pain and burning sensations. Some individuals, especially those above 40 years could experience pain in the affected area long after the rash is gone(post herpetic neuralgia).
Treated early(i.e, within 72 hours of the rash), Herpes zoster can be controlled with antiviral medications like acyclovir, famcyclovir or valacyclovir. After this period, as in your case, these medications are not going to be of much help.
Here is what you can do now, if you are not in a position to see a doctor immediately:
