In what circumstances will a prisoner be successful in a claim for deliberate indifference to his medical needs?

In the present case, the court does not find the required exceptional circumstances at this time. Although this court's review of this case indicates that plaintiff has a reasonable opportunity of prevailing on the merits of his claims, plaintiff has, to date, adequately demonstrated the ability to articulate his claims pro se. To prevail on his Eighth Amendment claims, plaintiff must present evidence demonstrating that defendants were aware of plaintiff's need for pain medication while recovering from his burn injuries but denied such relief. To prevail on a claim for deliberate indifference to serious medical needs, a prisoner must demonstrate that a prison official "kn[ew] of and disregard [ed] an excessive risk to inmate health or safety; the official must both be aware of the facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference." Farmer v. Brennan, 511 U.S. 825, 837 (1994).
