Medical Checks in DXB (Dubai)

Hello Fellow InterNations Members,
I'm a Brit living/working in Yemen, and due to take some Rest and relaxation in Dubai at the end of January and Early February. I need to make contact with some medical professionals to have some follow up checks done. I'm looking for recommendations for:

A dermatologist who specialises in moles
A physiotherapist or Osteopath; to help me with a shoulder/sports injury
Untra-sound specialist, for a follow up liver scan

Any support that can be offered will be most welcome
Yours, with thanks in advance
Richard
