Hi,Dear,Thanks for your query to HCM. Dear I read your query and reviewed it with context to your query facts. I understood your health concerns and feel Concerned about them. Based on the facts of your query, you seem to suffer from- LGV /Chancroid from your partner who had sinusitis but had a oral LGV or Chancroid infection from earlier oral sex with spread from other partners with whom she/ or he had oral sex. Possibility of Sinusitis partner causing groin lumps is only when the oral sex partner with sinusitis had earlier Chlamydia Tachomatis / or Pneumoniae Sinusitis ,which is known cause of Sinusitis in such high risk partners. Thus the answer is YES,your partner s Sinusitis has caused the groin bubo swelling on either side in your groin. Smear of oral mucosa or from secretions from post-nasal drip from your partner would fix this cause. Hope this would help you to reduce worry with your problem. Take care and wish you to recover fast and Live healthy. Hope this reply would help you to plan further treatment with your family and specialist doctors there. Welcome for any further query in this regard. Good Day!! Dr.Savaskar M.N. Senior Surgical Specialist M.S.Genl-CVTS
