Red Feet

Hi.
Can you please help me?
I’m really worried about my feet.Last Wednesday I took off my shoes and socks after work.
I notice that the top surface of both feet had tiny pink dots and was very dense.
I figured it was just athlete’s foot.
I put Lotrimin on that evening.
Later that night I soaked my feet.
Once I took my feet out from soaking, they were burning very bad for a couple of minutes.
I went to the doctor the next day.
She noticed that the feet were pink, but got really red when I stand on them, especially for a long period.
She perscribed he an anti-biotic and ibuprofen.
She figured it was just athlete’s foot, but didn’t seem sure.
The next day I went to see a podiatrist.
He figured it was just a reaction to foot fungus, but I wasn’t convinced that he seemed completely sure either.Any ideas?
The only things that were different was I took stool softeners earlier that week, was on my feet on Monday and Tuesday for long hours, and I recently switched fabric softener.Please let me know.
It is day 4 and they are still the same (red, especially when standing up, and all toes remain pink.
THe big toes seem somewhat swollen or firm).
