What can you tell me about dermal hypersensitivity? My dermatologist has recently diagnosed me with this, however, I have yet to meet back with her and am trying to learn more about this. I have had these red small bumps for nearly a year which itch and persist even after using bethamethasone (SP?) on them.
Thanks for your query. I have gone through your query. The dermal hypersensitivity reactions can occur secondary to many reasons example, to dust, food, soaps or insect bite. Nothing to be panic, consult a good dermatologist and get it evaluated. If you are not responding to dexamethasone, we can try other steroids like clobetasol and other Chat Doctor.  To confirm the diagnosis get a skin biopsy done. You need to ask this question in dermatology or skin diseases section. I hope I have answered your query. Take care
