Welcome to health care magic.
1.There is no exact location or description about the lump you have given in your history, the symptoms are generalised.
2.In this case what i would do if you are my patient, i would have examine you, abdominal palpation, an
ultrasound abdomen and pelvis will be ordered.
3.Ultrasound will give status of the all crucial organs and any infective or chronic process status, and pelvic causes can be assessed also.
4.After that depending on the findings the treatment depends upon.
5.Mean while have healthy diet, avid junk,spicy foods, plenty of water - that would help. Good luck.
Hope i have answered your query.
Any thing to ask do not hesitate. Thank you.
