( CNN ) -- Interim Egyptian President Adly Mansour sent a letter to the family of jailed Al Jazeera journalist Mohamed Fahmy on Sunday telling him that Fahmy `` will enjoy all his rights guaranteed by Egyptian law . '' Mansour also ordered Egypt 's interior minister to follow up on Fahmy 's health condition and `` to provide all possible care . '' Fahmy , a former CNN producer , injured his shoulder before his arrest in December while working as bureau chief for Al Jazeera English in Cairo . He 's complained about not getting proper medical treatment while in prison . He says that because of the lack of treatment , he no longer has full use of his right arm . On Saturday , Fahmy , escorted by heavily armed , balaclava-wearing guards , arrived at a civilian hospital for the first time for a shoulder scan . Friends and family talked to him through the steel mesh of a prisoner transport vehicle before he was taken inside , where they had more access . The visit by family and friends `` put him in a good mood , '' said Fahmy 's fiancee , Marwa Abdel Magid . `` It 's the first time I 've seen him smile since he got arrested . '' Fahmy , who was seen barely able to lift his arm during his examination , had MRI and CT scans at the hospital . He said he and his colleagues -- Al Jazeera correspondent Peter Greste and producer Baher Mohamed -- were in good spirits . They also now receive daily newspapers to alleviate the boredom while they wait for their trial to end . Fahmy said he wanted more time outside his windowless cell with his colleagues . He also wants his case resolved faster and more time with his lawyer than the 45 minutes he receives before each session . In the letter , the interim President promised to `` make sure the case is resolved quickly and that justice is achieved according to the law . '' Fahmy , Greste and Mohamed have been detained for almost three months after security services raided their workspace at the Marriott hotel . The Egyptian government says they distorted their coverage in favor of ousted President Mohamed Morsy and the Muslim Brotherhood , which is designated a terrorist group in Egypt . They are on trial , charged with spreading false news and belonging to a terrorist organization , which Al Jazeera strongly denies . The case has been widely condemned internationally as an attack on free speech . Their trial will resume on March 31 .
