Skin rashes red colour. Other symptoms.

Hi doctor, I got skin rashes on my hands and legs starting Monday night after eating dinner. I first thought it was a food allergy, so I had a cetrizine and slept off. However, the rashes became more prominent in the morning. I applied an anti fungal cream over the spots, and it seemed to reduce during the day. However, in the night it resurfaced, especially around my wrists and hand area. I went to the emergency doctor at a nearby hospital. He gave me avil injection plus tablets and lacto calamine variant. However, next day it didn't help. I came to the conclusion that the anti fungal cream helped, and it's not an allergic reaction. Seems to me like it's similar to a jock itch, but it's not around my groin. Its around my hands and legs. I'm pretty physically active and have a good diet and hygienic too. Attaching photos. Please advise next steps. I do not have a fever or any other symptoms.
