The Warriors have no timetable for center Kevon Looney’s return from right hamstring tightness. And given the nature of the injury, they aren’t quite sure when they’ll have a better idea of when he’ll be back.

After returning to San Francisco on Tuesday, Looney, who missed the past two games, is expected to meet with a team of specialists to evaluate a neuropathic condition tied directly to his recent hamstring issue. The Warriors hope to have an update after team doctors discuss Looney’s condition with specialists, but it’s unclear whether that will yield much clarity.

In a phone interview Tuesday with The Chronicle, Dr. Vernon Williams — a sports neurologist and founding director of the Center for Sports Neurology and Pain Medicine at Cedars-Sinai Kerlan-Jobe Institute in Los Angeles — said that little can be gleaned from Golden State’s description of Looney’s ailment as a “neuropathic condition.”

“That could be pain, burning, numbing or tingling in character,” said Williams, who has not worked with Looney. “Or he could have a degree of weakness because nerves supply muscles. It’s possible for someone to have weakness as part of their symptom. The description is an extremely non-specific description.

“So, just based on the description of the neuropathic condition, it just tells us that it involves nerves or the neuro-structure. … We have no idea.”

Warriors head coach Steve Kerr told reporters Saturday that Looney has had the condition for “a couple of years, and it’s something that he’s been able to play through. But in this particular case, the condition is affecting his hamstring.

“The hamstring is sound. The MRI is clean, but it makes it trickier that it’s a neuropathic issue.”

According to the American Chronic Pain Association, neuropathic pain is a chronic condition that occurs when nerves become damaged or injured. Pinpointing neuropathic pain can be difficult because it has few, if any, objective signs. Doctors must rely on a patient’s description of the pain to identify its cause and try to find a remedy.

Williams said that, if the neuropathic condition is related solely to pain, it sometimes can be taken care of in a matter of days. But if the condition affects motor function, it sometimes takes much longer.

This could be a scary prospect for the Warriors, who enter Wednesday night’s game against Phoenix at Chase Center with a 1-2 record. Looney, who signed a three-year, $15 million deal with Golden State in July, is a stabilizing force for a thin front court.

With Looney and Willie Cauley-Stein (foot) out, Golden State is scraping together a center rotation of Marquese Chriss, Omari Spellman, Draymond Green and Eric Paschall — none of whom is a true center. Green (6-foot-6) started at center in Monday’s win over the Pelicans, a sight typically found only in playoff games.

“Based off the Warriors’ description, all we know is that there’s some nerve component that’s going on,” said Williams, who has consulted for the Lakers. “There’s some dysfunction of a nerve or some abnormal activity of a nerve, and we don’t know what nerve it is or if it’s a group of nerves.”
