Telogen effluvium symptoms and conditions

I am a healthy 58 yr old woman. On May 20 2008, I went to the dentist to have two small fillings done. At the time of the shot I experienced what felt as though I had received an electrical jolt because the shot hit my nerve. This jolt radiated down to my ovaries. I complained to the dentist instantly. Right after the visit I started noticing that my hair was thinning. On June 17, 2008 at my normal hair appointment I commented to the beautician that my hair was thinning. On June 27, 2008 at the second visit to the dentist I experience the same problem from the shot and again told the dentist of problem. By July 18th I noticed some extreme hair loss in two locations on my scalp. I pointed out my hair loss condition to the Dermatologist at the Cleveland Clinic on July 18, 2008 he referred me to a hair loss specialist. On September 2, 2008 I meet the specialist she stated that the hair loss was caused by some extreme stress to my system. I told her about the dental work and my reaction to the injection. She said that could have been the catalyst that started this problem. The doctor said if there is some "shock to the system", as many as 70% of the scalp hairs are then shed in large numbers about 1 to 2 months after the "shock". This sudden increase in hair loss, usually described as the hair coming out in handfuls is called acute telogen effluvium. Has anyone else had a similar experience?

I've been taking Yasmin since March of 2006... My periods have always been light and short in duration (3 days). In the past few months my periods have been 6-7 days with severe cramping... In addition, my hair started shedding excessively about 2 months ago and I've probably lost at least 1/3 to 1/2 of my scalp hair! My doctor tested me for thyroid problems, but determined that the hair loss was telogen effluvium (caused from stress). I have also been having issues with my stomach being upset and have lost nearly 15 lbs since I first started taking Yasmin. If anyone else has ever experienced hair loss from Yasmin, please let me know. I've read articles that have stated you can lose hair when stopping Yasmin, but I'm wondering if taking it could be causing my hair loss???
