Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain red itchy bumps on your body that spread to you after 2 days after camping can be due to causes like:
-Any bug or insect bite that was toxic enough to cause generalized
allergic reaction..
-It can also be due to
Mite infestation causing Scabies..
As the bumps are still present even after treating for scabies then I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like blood tests and microscopic examination of the scrapings from bumps can help in diagnosis and treatment can be done accordingly..
In case if it is an allergic reaction anti allergics like Allegra or
benadryl,
steroids and also injection of steroid for faster resolution along with steroid ointment and cool compresses over red bumps can help..
In case of Scabies another course of medicine like oral
Ivermectin and topical Premethrin lotion can help in relief..
Also keep your mattresses in sunlight and wash all your beddings, clothes etc and also disinfect them..
Hope this information helps..
Thanks and regards.
