Im afraid its going to reach the chest and tighten up my breathing.
[|AI|]  Hi, Thanks for using Chat Doctor. Since the rashes are spreading, and you have not mentioned its appearance and associated symptoms, it should be evaluated for the cause. Usually skin rashes does not affect systemic if it is due to dermal problem. If any systemic association or the rashes appeared due to systemic problem then there are chances of other organ involvement. It may be due to allergy or due to infection or due to any Chat Doctor.  Kindly let us know about above-mentioned characteristics, investigations you have,
