What causes Neuralgia?

[chamber1]

My sister in law who is a healthy woman of 52.  She is a vegetarian, a runner and in good shape.  She definitely takes care of herself. I guess just recently to her recollection she told the doctors that she slightly hit her head with the trunk of her car.  There was no consequence and she forgot about it.  Then just recently started having excrutiating headaches and undescribable body pains in different parts of her body.  She also had a stabbing pain on the side of her head.  She did go for a cat scan and blood tests that came back negative.  No tylenol or ibuprofen was helping with her pain  so the hospital told her it might be stress and gave her morphine.  That did help with the pain but she couldn't function properly.  She went to see her regular doctor today and the doctor diagnosed her with Neuralgia.  Can Neuraligia come from nowhere and hit you like this or was it caused by the little bump on her head?

Nancy,

Thank you for your comments. I almost forgot that I posted this.  She seems to be  feeling better because of the medication she is taking.  No more body aches and stabbing headache.  I'll be seeing her tonight and mention that you commented on my post.  

Thank you and all the best to you,

Cathy

According to what I've read Trigeminal Neuralgia can be caused by a blood vessel or vein pressing on the Trigeminal nerve, by MS, by tumors, or by damage to the Trigeminal nerve during a surgical procedure.  I'm not really sure about a bump on the head.

There are different types of "neuralgia" -- you may want to post your question on the Neurology community or do a search on this website -- if you are asking your question about "neuralgia" in general.

All the best,
Nancy
