I just did a little research- the info below showed up here: http://www.prozactruth.com/clonazepam.htm
Klonopin withdrawal - Varicose Vein - Unusually swollen veins near the surface of the skin that sometimes appear twisted and knotted, but always enlarged. They are called hemorrhoids when they appear around the rectum. The cause is attributed to hereditary weakness in the veins aggravated by obesity, pregnancy, pressure from standing, aging, etc. Severe cases may develop swelling in the legs, ankles and feet, eczema and/or ulcers in the affected areas.
Also this, from the TRAP website, http://www.non-benzodiazepines.org.uk/dangerous-drugs.html
Here is a list of withdrawal symptoms I had pretty much on a daily basis throughout the taper and some for several months afterwards.
Sore gums(this was a sx that actually went away as I got lower on my dose)
Wheezing(this also was a sx that went away when I got lower)
Constant runny nose and other asst sinus problems
Weird bulging vein thing especially in my hands
Very low temperature
Anxiety-racing thoughts etc
- You might want to click on the second link for the rest of this. It's some guy's klonopin experience and it goes on. It might help to look at the whole thing.
Edit: Deactivated link to another benzo forum.
