Hi Lilian,
You can certainly call for an earlier appointment if you are too worried about this pain you have,but waiting till early March is not that long await.
Some cysts contain debris or areas of solid tissue; these are referred to as “complicated” cysts. Complicated cysts have some increased chance, although small, of being cancerous. Ultrasound–guided cyst drainage may be recommended by your doctor or by the radiologist in order to relieve pain caused by the cyst or to evaluate a complex cyst further.
Avoiding caffeine (Chocolate, coffee,cola ) can ease the pain considerably.
Best wishes..and good luck.
