Hi Sharyn, with your MDS, your immune system is weakened. So, having an abscess and a UTI is compounding your misery in part because of your immune system being compromised.
I’m concerned when you mention that you have a abscess and also a UTI because both can become very serious quite quickly if not taken care of with antibiotics. I’m not sure where your abscess is located but even in the mouth these can go systemic and need to be treated. You may have a lower white blood count which means your infection fighting cells are low…that leads to these infections.

Yes, please call either your primary care physician or hematologist and explain what’s happening. You should have some bloodwork run and treatment started for your two infections. You also deserve find out if your MDS is progressing. If your hematologist is hard to track down, do you have an option of getting a second opinion?
