Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of
severe itching along with sore nodules over the scalp can be due to bacterial infection of hair follicles known as
Folliculitis..
It can also be due to
fungal infection leading to Seborrheic dermatitis in case if there is also white flakes or dandruff along with sore bumps..
It seems most probably like Folliculitis..
The medication HC 2.5% cream and Clobex spray are both steroid based and will help in reducing itching and sores..
But you may also ned antibiotics or antifungals depending upon the exact cause..
I would however suggest you to consult a Trichologist and get evaluated and a thorough clinical evaluation can help in diagnosis and treatment can be done accordingly..
In case of Folliculitis you can be advised to take
oral antibiotics, along with anti allergic like Allegra and continuation of coal tar shampoo and steroid lotions..
In case of fungal infection antifungal shampoo containing Ketooconazole, sulfide, coaltar, zinc,
salicylic acid etc can help..
Hope this information helps..
Thanks and regards.
