Declining health and conflict with Stalin: 1920–1923

Lenin became seriously ill by the latter half of 1921, experiencing hyperacusis, insomnia, and regular headaches. At the Politburo's insistence, in July he left Moscow for a month's leave at his Gorki mansion, where he was cared for by his wife and sister. Lenin began to contemplate the possibility of suicide, asking both Krupskaya and Stalin to acquire potassium cyanide for him. Twenty-six physicians were hired to help Lenin during his final years; many of them were foreign and had been hired at great expense. Some suggested that his sickness could have been caused by metal oxidation from the bullets that were lodged in his body from the 1918 assassination attempt; in April 1922 he underwent a surgical operation to successfully remove them. The symptoms continued after this, with Lenin's doctors unsure of the cause; some suggested that he had neurasthenia or cerebral arteriosclerosis. In May 1922, he had his first stroke, temporarily losing his ability to speak and being paralysed on his right side. He convalesced at Gorki and had largely recovered by July. In October, he returned to Moscow; in December, he had a second stroke and returned to Gorki.
