Groin Rash,thigh Rash,red,splotch,no Pain,no Itch
From the image given, it seems that you might be having folliculitis of the pubic region. They usually occur due to secondary infection of razor burns.
Shaving the groin area, can result in cuts which can cause - bacterial infection of the hair follicles.
You can get relief by using a ointment called Mupirocin, which can be applied locally.
Hot, moist compresses may promote drainage of the affected follicles.
In addition, the inflammation can be resolved by using a NSAIDs like ibuprofen or Naproxen.
If they do not resolve soon, you might need prescription antibiotics (given by your doctor) to treat the infection, and this will help to clear them.
Here are a few tips to prevent such occurances again:-
1. Purchase good razors. The more times you must go over the same area, the more likely you are to get razor burn.
2. Take your time; don't rush through. Shaving should be no more often than once a day at the end of or after a shower or bath. If the skin is softened from the steam, it will make your results much better. You want to wash the area to be shaved before applying any type of shaving cream. The razors weight should be enough pressure to take off the hair. You should not push into the skin.
3. Stick with a shaving cream as opposed to a shaving gel.
4. Apply lotions 30 minutes after finishing your shower. This will allow for your pores to close before and minimze irritation.
5. Treat razor burn with aloe vera gel or very cold water. The aloe vera allows for protection from the environment and has analgesic qualities that reduce swelling, soothe the irritation, and form a barrier which protects the skin from infection and promotes healing.
6. Cortisone cream will also help with the redness and discomfort.
7. Also if you cannot get cortisone cream or aloe vera gel you can just use cold water and a wash cloth and XXXXXXX dry.
