blisters under rings

Sa

recently my mum passed away and she left her engagement ring and one with diamonds representing my siblings and i on it, they are both gold rings and as i was told to wear them i keep them on my opposite hand to my wedding rings (thats where they fit) my wedding rings happen to either be white gold or silver while mums rings are gold, I've never had any problems with my own rings but suddenly i have started to get what looks like small blisters on my finger where the rings sit its really confusing as they fit perfectly and are easy to take off and put on but suddenly theres blisters. i take them off to wash my hands and stuff so i have no idea what its from. i love wearing them as they make me feel like i have a piece of mum woth me always but I'm not sure if its the rings causing the blisters. i do remember when i was little gold earings caused my ears to get sore and bleed, even now they can get a little tender after a short while (i got a set of gold earings from my great aunt for my birthday but i rarely wear them as they hurt after a few minuets but haven't bled yet like when i was littler) I'm wondering if maybe i have a gold allergy like my aunts or something. has anyone else had something similar?
