Hello,
Thank you for asking your query at DoctorSpring.
The two problems are completely unrelated. Initially you developed hemorrhoids due to constipation. There was bleeding due to hemorrhoids. You did take the rite measures to take care of it and taken the rite medications. But, what you have developed now is not anything related to hemorrhoids, its mass in lower abdomen basically your pelvis. Most probably could be fibroids. Sometimes fibroids don't present with bleeding per vaginally.
Its important you take a USG abdomen. Continue your treatment for hemorrhoids, don't stop it. For the pain you can take Tylenol. I suggest you visit a gynaecologist soon.
Hope this helps. Please feel free to ask follow-up questions
