Chronic Welt On Right Side Of Spine, With Two Blisters, Swollen Lymph Node, Prevention

I have a chronic welt about quarter-size in the lower quadrant of my torso to the right of my spine that contains two small blisters. It lasts for about two weeks and dries up after repeated cleansing with alcohol . While the welt is present, my right lymph node is swollen. It always presents itself in the same pattern, in the exact same location, and the blisters are directly beside one another. I thought it was a bug bite at first until it came back.

Hi,
After reading your history it appears that you might have developed allergic dermatitis to some contact allergen or ther emay be possibility of eczematous lesion also.
I advise you to not pinch or pop the area otherwise these areas are very prone for getting secondary infection. You can apply an steroid cream such as cortisone cream. If itching is present then can take benadryl accordingly.
You can go for skin biopsy of the area so that exact diagnosis can be made out.
