Hi, I have these red itchy bumps on my arms and legs that comes and goes, at first they started off small then into welps and now they are the size of an egg. Plus they're starting to hurt like kind of sore but no skin is broken. What could this be?

Thanks for posting your query.
You are most probably suffering from urticarial rash or allergic dermatitis which can occur due to contact or food allergy or exposure to any medication or chemical product.Occasionally sun damage could be the cause if the lesions are only on sun exposed areas. Due to itching and scratching the skin inflammation worsens and soreness can be felt .
The next best step would be to consult your dermatologist who can evaluate and confirm the diagnosis , rule out the potential causes and start treatment accordingly.
The basic treatment would be application of soothing lotions like calamine , avoiding harsh chemicals , sun exposure or any new product( suspected allergen) and oral anti allergic medications like fexofenadine or cetrizine .
This would also decrease the itching and hence allow the inflammation to decrease, however sometimes steroid based creams like hydrocortisone might be needed for quick relief.
Apart from this depending on the cause the curative treatment can be started.
So please do not worry but nevertheless do seek prompt consultation with your dermatologist / physician .
Hope that answers your query.
Please feel free to ask any further queries.

I also forgot to mention that the bumps don't appear until well after I start scratching my arms or legs, and then the small bumps seem to spread becoming like welps, and then into XXXXXXX hot tender to the touch sore red bumps. They are very irritated, and when they come back it's in the same spots, like they haven't gone away fully.
