Is It Safe To Take Ambezim For Bilateral Joint Effusions?

I AM A FEMALE 39. FOR THE PAST 6 MONTHS I'VE BEEN IN A LOT OF PAIN. FIRST I WAS TREATED OF SCIATICA WITH LASER AND ULTRARED. AFTER A MONTH WITH NO RESULTS THEY DID MRI FOR LUMBAR REGION AND FOUND OUT I HAD SIGNIFICANT BACK MUSCLE SPASM. THEY PRESCRIBED ME LYRICA, THIOTACIDE COMPOUND, IBUFLEX AND FASTUM GEL. AFTER A WEEK I HAD ANOTHER APOINTMENT WITH THE DOCTOR WITH NO IMPROVEMENT AND A LOT OF PAIN SO THEY DID A HIP MRI AND FOUND BILATERAL JOINT EFFUSION SO THEY PRESCRIBED AN EXTRA MEDICINE CALLED AMBEZIM G. I AM STILL WITH A LOT OF PAIN AFTER ANOTHER WEEK. I CAN'T TAKE SEAT FOR LONG MY KNEES ARE KILLING ME AND MY HIPS AND THE PAIN MOVES FROM RIGHT SIDE TO LEFT SIDE. MY QUESTION IS . AM I GETTING THE RIGHT TREATMENT. IF SO HOW LONG TO SEE SOME RELIEF? I PAID A LOT OF MONEY IN PRIVATE DOCTORS BUT I AM HESITANT AND WORRIED. I WILL BE GOING IN 2 WEEKS ON HOLIDAYS AND I WANT TO GET BETTER. COULD I PLEASE HAVE AN ANSWER
