It sounds like a type of dermatitis (such as psoriasis or eczema). Lubricants and aloe may help some as you have noted. However, you may need some steroids to make the swelling and lump go away. You can try weak Hydrocortisone cream (you can get OTC), but don't get any in the eyes. If that doesn't work, you may need to see a doctor about some stronger creams/ointments.
There is always a first time. Often, it can be seasonal as well. There are indications that sunlight helps. Seeing a dermatologist would be the best thing if this is becoming a chronic problem for you.
