Intermittent Claudication
"I experienced what is described as &quot;blue/purple finger(s)&quot; in my left hand. After an intensive vascular examination, this was determined to be caused by vascular spasms. After being prescribed Trental by my doctor. The blue/purple condition of my hand fingers returned to normal skin color in about two or three days. There were no noticeable side effects and when I stopped taking the medication, the condition did not return to &quot;blue/purple&quot; and to date remains a normal skin color."
