Hi, I have a single, oval-shaped patch on my left forearm that has a white bump in the middle. Unfortunately I m colorblind so I can t determine the exact color, but I d say it s either a red or brown color. I work as a landscaper so I m outside 99% of the time and I live along the Jersey Shore in New Jersey. It showed up 4 days ago, but when I first noticed it I thought it was just a bruise as the white bump wasn t that prevalent on the first day so I didn t pay it much mind. The next day I noticed it was a little different looking so I looked closer and I had a feeling it wasn t a bruise as the white bump was a lot clearer and there wasn t any black and blue areas normally associated with bruises. I even lightly pressed on it in different areas to see if there was any pain and there was none, which is something I ve always felt with bruises. Besides just having the patch on my arm, I haven t noticed anything else. There s no pain, no illnesses, no nausea, no itching, no burning, and so on. After doing some research online several websites have said that it could be an insect/spider bite, but I haven t been able to match exactly what it is so far. I ve looked at pictures and symptoms, but every one I ve seen doesn t match what I have. The closest thing I ve seen is Lyme s Disease, but my patch doesn t have an extra ring around the outside like every picture of Lyme s Disease I ve seen has. Also, I saw a few times that if it has a white bump in the middle, it s most likely a spider bite. I looked at the poisonous spider symptoms and mine looks nothing like any of the top 3 or 4 so I don t think it s one of those. Some mentioned it could just be a mild spider bite or just an allergic reaction to whatever it is. It hasn t appeared to have gotten any better since I noticed it so I m getting worried about what it is. I just lost my health insurance as I just turned 26 on April 26 and was dropped from my parents health insurance so going to a hospital or a doctor is kind of a problem for me right now.
