R. Kelly Says He's Having Health Problems in Jail

R. Kelly is going back to court for a second try at getting out of jail pending his various trials, claiming his health has been compromised behind bars.

Kelly's lawyer just filed new legal docs, obtained by TMZ, in which they outline his various medical issues, including numbness in one of his hands, anxiety and an untreated hernia.

The lawyer, Steve Greenberg, claims the singer is not receiving adequate medical treatment in the facility and calls the conditions of his confinement "stifling." As for why ... Greenberg says, "Although he lives and has lived with two lady friends, only one of them is allowed to be on his visiting list, and after 90 days he's required to switch." He confirmed to TMZ, the woman who is currently on the list is Azriel Clary -- so Joycelyn Savage has to wait it out before she can visit Kelly.

The docs also try to assure the judge nothing untoward will happen if R. Kelly gets out. The docs vow the singer will not tamper with or intimidate witnesses. Greenberg also claims R. Kelly is not a flight risk ... he has a passport which does not contain a single stamp showing travel, because he doesn't really go outside the U.S. Besides, he wouldn't even have access to his passport.

The judge has yet to rule.
