Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain sudden appearance of itchy rashes all over the body can be probably due
allergic reaction to some unknown allergen while other cause can e
Scabies that is a tick infestation infection..
In case if you are unable to
consult a Dermatologist I would suggest you to consult an Allergist or an Infectious medicine specialist and get evaluated and he can do a thorough clinical evaluation and also necessary investigations as per the suspected cause and treatment can be planned accordingly..
As of now you can take anti allergics like Allegra or
benadryl and apply a
steroid ointment over the bumps..
Cool compresses or cold water bath can also be relieving..
In case if scabies is diagnosed the physician can advise you anti-mite or mite killer drugs like Permethrin and Lindane lotion..
Hope this information helps..
Thanks and regards.
