Welcome and thanks for posting your query to Healthcare Magic.
As per your query you have red bumps below navel, legs after starting Ery tabs and there is no improvement with hydrocortisone cream
After reading your query it appears the possibility of "Folliculitis" meaning inflammation of the hair roots.
Our skin is always been harbored by bacteria.But due to any friction or trivial touching with continuous exposure to water there can be entrance of the bacteria in the skin. Once these enter these proliferate to cause inflammation of the hair roots. The infection then spreads to side by roots and so results in red swollen area with pus in it.
For the prevention and betterment kindly follow the suggestions below:
- stay away from hot and humid climate.
- Do not scratch any skin lesion or even try to touch unnecessarily.
-Apply any antibacterial cream such as fucidin
2 times a day in a very thin layer so that it should not be visible to naked eye.
-You can do cold
water compresses to reduce the intensity of itching.
-Do not scratch or rub the skin as it can lead to further aggravation.
-You can take oral painkillers such as paracetamol
round the clock to reduce the intensity of the pain.
In my opinion it can no be because of your antibiotics. Rather antibiotics are helpful in presenting further infection.It is better to consult a dermatologist
for best guidance.
Hope these informations will help. If you have further queries I will be happy to help.
"With good health wishes"
