I have a painful and swollen right forefinger knuckle that creates nerve pain and seemed to appear overnight. I have had it over 2 months and a doctor thought ganglion cyst w no xray or tests of any kind. I was given a compounded cream Diltiazem (lipoderm) 5% cream to put on my knuckle 2 times daily and have been doing so for over 2 weeks. The swelling is apt to worsen with use and creates more pain. Can feel under the forefinger as in nerve pain. Sometimes it starts swelling so that space between my forefinger and middle finger swells. I am right handed so I need another opinion as to what it may or not be. Even basic info. would help. Thank you for your time.
