Noticed Itchy Rashes On Lower Abdomen After Taking Multivitamin. Concerned
Regarding the rash which you are describing there are two possibilities. One possibility would be that this is some type of fungal infection. These types of infections don't usually travel or spread from one area to the next although they can sometimes be diffuse.
The other possibility is that this might be a viral type of rash. This is also referred to as shingles. Shingles rash usually will progress in a linear distribution. You can check online for images that might look similar. If this is in fact a shingles rash you should talk to your doctor as soon as possible to obtain antiviral medication to help this resolved quickly.
Thanks again for sending your question. Please let me know if you have any additional concerns regarding this matter.
