I Am 69 Years Old And Had A Hysterectomy When

I am 69 years old and had a hysterectomy when I was 32 I still have my ovaries. I just finished a 30 plus day is strong antibiotics for sinus infection. Today I am experiencing tenderness and pain in my far right side. I have had a lot of gas and about five bike movements could this be a cyst or inflammation from the antibiotic? I am very sensitive to meds
