Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain due to wearing a dangle in the belly piercing there has been hanging of the skin due to the weight of the dangle and it might has caused injury to the soft skin causing inflammation and formation of a hard area.. Other thing is that you might have got an allergic reaction to the metal used in the dangle leading to inflammation.. Nothing to worry, as of now you should not try wearing anything as due to swelling the pierced hole might have narrowed down you are not able to put the ring.. You can clean the area with an antiseptic solution and apply a combination of Triple antibiotic ointment and steroid ointment for relieving infection and inflammation.. Do cool compresses over the sensitive and hard area.. If there is pain tylenol or diclofenac can be taken.. Keep the area clean.. It will resolve almost in a week.. Hope this information helps.. Thanks and regards. Dr. Honey Nandwani Arora.
