Thanks for the query to H.C.M. Forum.
Carpal tunnel is formed flexor retinaculum anteriorly & carpus posteriorly. Median nerve
& flexor tendon pass through it.
This detail was necessary so that you understand easily.
Whatever the cause or disease , simple decompression of the tunnel cures the condition.
As in your case it is bilateral so synovectomy
may require .
But no need of fear as surgery is safe and only option.
