can you identify this strange blister? . what is a small blister-like flat bubble on my shoulder that causes no pain and no itchiness? it may have gone down a bit during the three weeks it has been there. no spreading and no additional blisters found. first i have ever noticed in my 57 years.
unfortunatelly it would not be possible for me (or any medical provider) to blindly identify this "blister" based solely on your description. you would need to be examined first-hand by a medical professional.
