I had what I thought was a spider bite on June 16 or 17th. It became infected and swelled quite a bit. I was going to see the Doctor if it did not get better, but it did go down. Now, it's still there a month and half later and a little sore, red, and about the size of a pencil tip and I'm wondering if I should see someone. A co-worker suggested it might be MRSA instead of a spider bite. However, it is much smaller now and I'm not sure if I'm over-reacting. Can you please advise on if I should see a doctor and which type of doctor to see? Thank you.

List of other diseases, conditions, or injuries and their treatment: H. Pylori - took PrevPak. Distal clavicular osteolysis - subchondral fracture in right clavicle.
Have a diagnosis for the current condition: no
Current medical status: small spider bite (I think)
Current medical treatment: None.

A “little sore, red bump” sounds like a skin inflammation but I can’t estimate if it is caused by a spider bite or something else. However, it is very unlikely to be a lesion caused by MRSA because MRSA causes skin infections that contain pus (abscess, pyodermia, impetigo, etc.).

If the bump is smaller now that means it is probably healing. You can wait for a few weeks to see if the bump heals completely.

You may want to consult a dermatologist for a precise diagnosis.
