My mother is 53 yrs old. Suddenly a morning she finds her both hands and feet swelling withsevere paint. It's one week today.

We have consulted a orthopaediacian, the test of arthiritis is negative, uric acid is with in limts, the doctor has said that there is no problem of bones.

my mother has also problem of skin disease sorosis, he said that this swelling is linked with skin disease

We have also consulted skin specialist, but he has said that it is not linked with skin problem

We are confused what is the problem

Please suggest us to which doctor we must go
