ANESTHETIC PATCH. hello, I'm 33+ & have the same problem from around last 4 yrs. In the beginning it started with needle pricking giving a dis illusion as some needle is left inside my jeans pocket. later in six months that spot became numb with almost symptoms resembling to u all. when I stand at the same place I feel as some acid like warm thing is dripping inside or some thread like thing has been pulled inside of my veins of that area, I cannot explain exactly. now from last 3-4 months I'm feeling lil bit pain in the area. In the starting I went to a Homeopathic Doctor & he told me it is called ANESTHETIC PATCH ( may be here in India). his medicine reduced the anesthetic effect in one or two weeks only but after two months of medication I started neglecting it. now I've started taking medicines again. So things to remember- 1) Homeopathy in India calls it ANESTHETIC PATCH.( don't know about rest of the world), 2) Homeopathic medicines act according to the symptoms of the disease( like for headache there is not a single medicine because headache can be due to gas trouble, high blood pressure, hunger. So medicine would be given accordingly). So it may take time for ur doctor to give u the effective medicine. 3) So Homeopathy, (when medicines given matches the symptoms) is quick acting but is a gradual process. you may need to administer medications for months or even for a year depending upon how chronic the problem is. Please spread the word to every one.
