Red bumps on left arm that scab over. pictures included

[ducriderpani]

About 3 months ago I noticed a small bump close to the inner crease of my left elbow. It’s not right in the crease, but more towards the outer, upper portion of my arm. It started as what seemed like the beginning of a small wart I could scratch the surface of it and my fingernail would catch and pull the top layer of skin off revealing a pinkish soft part of skin underneath it. It would cover itself again in 2 days or so, and I would repeat the process, pealing the top piece of skin off. It would grow each time this happened. Now, it about the size of a pencil eraser. The spot is harder skin, has a slightly tougher texture than normal surrounding skin. It will scab over if I scratch hard enough. It has bled a few times, but only a drop. I have pictures available, and will attach.

During this time period, I noticed a similar spot lower on my arm about six inches up from my wrist. I’ve left it alone for the past three months, except for last week, I inadvertently scratched it on something. It reminds me of how the bump by my elbow started. Started out small, but once I scratched it, it got bigger. It is now a larger red bump on my arm, as pictured with a slight flat scab across the top. When I run my finger over it, it is tough and obviously raised off my skin. There appears to be a small scab next to the bigger one that is the same kind of bump. I’ve left this alone for the last few days.

Any idea what this could be? How to get rid of it? It was fun to pick at it at first, but now it’s becoming obvious to the people around me that something weird is going on.

I’m 6'5", 190lbs- 26 years old. Eat healthy, clean foods. Mostly fish, chicken, and beef. Lots of vegetables and fruits. I work out with weights and cardio 4-5 times a week. I shower every day and use mild high quality soaps (dove, and Old Spice body wash.) I do consume moderate to heavy amounts of alcohol once or twice a week. I’ve had the same cleanliness and soap products for 5 years, and the same eating and physical habits for over a year. I’m not allergic to anything that I know of. Nothing significant has changed in my life other than moving from WA to Southern CA in November.

July 27th 2014 –

Upper arm legion appears to be minimizing. Still there. The bottom one has gotten significantly worse as seen in the new pictures. There is also a third dot next to the lower arm bump. It almost has a scab like thing on top of it. When it gets callused I am able to take a sharp knife and cut the top off. Then it builds the callus back up over a few weeks.

A friend gave me mupriocin ointment (2%) which I used for 1.5 months as directed. It seemed to help a little at first, but did not make significant improvements.

I’m in the process of getting health insurance as I recently fell of my parents. I’m looking for some help on figuring out what this is and if it can be solved with over the counter medications or ointments. Any and all information you can share will help immensely. Thank you.

Anything else on this? I will try the antibiotic cream soon. Any idea of the ideal stuff to use? The one by my elbow seems to have gotten better, however the lower one still has a scab.

It is possible this is psoriasis or it could be some sort of infection.  

I would go outside and get 30 minutes of sun a few times a week when possible.  Try treating it with an antibiotic cream.  If that doesn't work, try putting Vaseline on it twice a day.
