Are you having a swelling of the lower eyelid? If so it could be styes wherein there is a recurrent infection of the lining of the wall of the eyelid and the common causative agent Staphylococcus tends to remain in the root and keeps affecting again when the immunity is down. Homeopathic Medicine has good remedies to see that the stye is got rid of and also to see that there is no recurrent inflammation and infection of the same.
But a swelling of the sinus is not really that apparent as you are saying, whether or not the scope can go in or not. But if your Physician has diagnosed it as Sinusitis then it can be got rid of with Homeopathic medicines like Kali bich, Calc carb, Thuja etc.
