Itchy welts

Patient: I have been having itchy welts after waking up..i did have some kind of bug problem which i googled and says its called a carpet beetle larvae..i have cleaned my room and taken medicine after stopped for some time and again started…one to two first..but increasing day by day..and now it appears even during day..mostly on hands and back of my itches for some time and goes away…what concerns me is its getting more everyday and even on my lips and fingers…my lips and fingers gets swollen…and i dont think this is due t any bug because my even my two year old son and 6 month baby also sleeps woth me but they dont have any problem.

Symptoms: Itchy welts gradually increasing day by day
