Homeopaths and doctors in Brussels

Hello all! I recently moved to Brussels and unfortunately have to see a specialist (gastroenterologist). I was wondering if anyone can recommend a doctor/hospital..I went to Leopold park, because I live near Place Jourdan..only a consultation is extremely expensive (70e), especially for an intern ;). Also, I prefer homeopaths so if anyone has experience with them I would be grateful for all suggestions, advice and help I can get.
I forgot to add, I need an English speaking doctor..

Thank you very much!
