I Am 73 Years Old. Just A Couple Of Days

I am 73 years old. Just a couple of days ago my lips started bothering me. They were very swollen. I took an over the counter medication for two days and the swelling went down. But they still hurt a lot. I am keeping them moisturized with lip balm. When I smile, or try to, they hurt. I have lymphedema in my legs from the knees down to my toes. Other medical conditions: depression, glaucoma, psoriasis.
