Hi, posting again.
Woke up 5 days ago with a red patch on my right shoulder...it was slightly raised with the rest of the skin...doesn't itch or hurt, nothing, just there...is it an insect bite or allergy or rash or what? No other similar patches. Now the redness around it has died down and the place of the bite is more visible...no symptoms but since yesterday my right arm has been a little sore. Should I show it to a doctor?
