Doctors in Kolkata have successfully treated a 35-year-old schoolteacher who arrived with severe pain, tingling and numbness in his right hand, accompanied by bluish discolouration of several fingers. With the risk of permanent damage to the limb increasing by the hour, timely diagnosis and intervention became crucial. 

A critical vascular emergency initially appeared to be a possible cardiac or neurological problem soon became serious when the man was admitted with a history of hypertension (on Telma AM), presenting with a three–four day history of persistent tingling, numbness, and severe pain in his right arm and forearm. He had also developed bluish discolouration in the nail beds of three–four fingers.
