If you broke your toe and left it untreated could it cause infection throughout your entire body like having intense cranial pressure that feels like a sinus infection with no infection present?

Broken toes are usually very minor injuries and there are usually very few complications. If you break your toe and leave it untreated, it usually cannot cause infection throughout your entire body. However, open or compound toe fractures have the potential to cause infection because there is a break in the skin and the bone is exposed. Open toe fractures must be treated to prevent infection and can only be treated by a physician using antibiotics and surgery. If you have an open toe fracture or are worried about the possibility of infection, you need to see a physician as soon as possible.

What is the correlation with HIV and CD4 cells?

After infection, the CD4 count measured in blood generally reduces in the first month or two and then recovers, but not to the pre-infection level. Then, usually over many years the CD4 count reduces until HIV advances to cause symptoms. Anti-retroviral treatment stops the decline in CD4 cells which then usually recover and get stronger again. With HIV there is a lot of individual variability in how fast this takes. Some people need treatment soon after infection and other can still have a strong CD4 count after 15 years without treatment.
