Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain severe itching all over the body also known as Pruritis can be due to
allergic reaction to some unknown allergen and common allergens can be allergy to any food or medicine or can be due to
Contact Dermatitis due to contact of the skin to any irritant like detergents, soaps, skin cosmetics, latex , leather etc..
In case if there is formation of small bumps and rash also it can be due to Folliculitis or hair
follicle infection..
It can also be due to
mite infestation causing Scabies..
As of now you can take anti allergic medicines like Allegra, Benadryl, Claritin etc to relieve the symptoms..
You should consult an Allergist or
Dermatologist and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis and treatment can be done accordingly..
In case of allergic reaction you will be given injection of steroids followed by
oral antibiotics and anti allergics to relieve the symptoms..
In case of Folliculitis antibiotics,
topical antibiotic and steroid ointments and anti allergics will help..
In case of Scabies topical Premethrin lotion and oral Ivermectin and anti allergics will relieve..
Hope this information helps..
Thanks and regards.
