Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain a thick, raised, round and itchy
rash over the torso seems to be most probably Eczematous
Dermatitis or Eczema and can occur due to bacterial or
fungal infection,
dry skin etc
I would suggest you to consult a Dermatoogist and get evaluated and a thorough clinical evaluation and investigations like microscopic examination of scraping from the lesion and blood tests can help in diagnosis and treatment can be done accordingly..
You can be advised to keep the area moist by using emollients..
You can be advised to apply
steroid ointment over it..
A combination of antibacterial and antifiungal ointment can be advised..
You can also be given anti allergic medications..
Keep the area dry and clean and avoid wearing tight clothes..
Hope this information helps..
Thanks and regards.
