I am a 29 year old, Caucasian male. A few months ago, I saw a Dermatologist and tested positive on a nasal swab for MRSA. He told me that it shouldn't be a big deal and it is just part of my normal flora since I was asymptomatic.
This past Saturday, I developed a rash on my left shin about the size of my palm. It does not itch and has not opened up or wept, but is painful to the touch. It has worsened since it first appeared and is now dark purple/red and spread down to my ankle. I went to my Family Medicine practitioner first thing Monday morning and he immediately diagnosed it as MRSA, without any cultures. He took a swab, however, of the outside of the rash and sent it off to be grown. He prescribed Clindamycin 300mg qid and told me to keep it elevated. The preliminary results indicate that I definitely have staph, but it might not be MRSA. He now doesn't seem quite sure what it is and wants to biopsy it, since it still hasn't developed pustules. Some other symptoms, which I have been experiencing lately are unexplained weight loss to the tune of 35 pounds in the last month. I also have joint/bone pain and reoccurring flu-like symptoms. I figure that it is just my body fighting off an infection, but now I'm not sure if it is an infection it is fighting. Is it possible that the swabs are just picking up the normal Staphylococcus aureus that I've tested positive for in the past? Would a biopsy be the next step to figuring out what this is on my leg?
The only pictures I have found online that match what is on my leg are for leukemia. Is it possible that my doctor is doing to biopsy to check for this? He didn't seem like was wanted to share his ideas at this moment. I haven't had recent blood work since this started, but I charted my blood work over the last two years and I have consistently had low MPV, low neutrophils, and high lymphocytes. Could this be of any use in explaining what is causing my current issue.
Thank you for your time and thoughts.
I also posted this in Dermatology in case it isn't leukemia.
If you have petechiae, then you might expect to see also bleeding from the gums, or else easy bruising anywhere.
As far as weight loss, when it is from advanced cancer (cachexia) then loss will occur no matter how much a person eats - or else it would simply be a matter of hooking up to an IV to provide adequate nutrition and no one would waste away.
As far as the unintentional rapid weight loss, there is a list of things that can cause that - but it would be reasonable to assume at this point that the same underlying condition is causing everything. Bananas and greens wouldn't do it.
If the weight loss is continuing I'd definitely exercise in order to preserve muscle mass as much as possible.
Also, fat soluble substances such as some hormones and even toxins are stored in fat cells. When fat is lost, they get released and can cause effects.
