Get that looked at: Any infection on the skin from a puncture wound by an insect or animal which is becoming red, swollen, and hot to the touch is potentially showing the initial signs of an infection. What you don't want it to be is a MRSA type of infection so you'll want to get ahead of this thing quickly. Clean the area with soap and water at least 2-3x daily until you see the doctor and stay well hydrated.

Rash: It sounds like you may have been exposed to a toxin such as poison ivy or oak. Try not to sratch the area. Take an antihistamine to see if it will help. Use Aveeno (oatmeal) in your bath water and try a mild hydrocortisone cream. If this doesn't help see your doctor for an assessment and consideration for steroids taken by mouth. All the best and I hope you feel better soon.

I have a rash on my leg. Thought it was from a mosquito bite, but now its swollen and red and I m afraid it's a spider bite. Could you take a look?

Not a spider: There are no venomous spiders in NY. Unless you saw and felt the spider attack you know it is something else. There are hundreds of different causes for a rash on your leg. Does it itch? How long? Best result will be obtained by a trip to a dermatologist. Meanwhile you can try hydrocortisone cream.

Allergic reaction: If it is an insect bite there will be local redness around the site of the bite. It should subside after 3 days. If it progress then it would be advisable to have your doctor look at it to make sure it is not secondarily infected. Cool soaks and topical benadryl (diphenhydramine) will help control the symptoms.

Got bitten by something on back of ankle 24 hrs ago looked like mosquito bite, now has weird scab very swollen and red rash spreading around foot..

Spider bite: Sounds like a spider bite. I am not sure what types of spiders are common or poisonous in Australlia. If poisonous spiders are common around your town, I would visit the doctor. If you experience severe pain, abdominal cramping, or the bite site begins to open up like a wound, immediately go to the hospital.

Bedbugs or virus: While viral illness could be the cause, don't forget about bedbug ties. Also need to consider what medications/vitamins have recently been taken.

Followed peds advice: I would trust your pediatrician since he saw the rash. If it is a heat rash, there really isn't any treatment other than prevention by keeping the skin cool.

I have been getting rashes all over body (looks like clusters of mosquito bites) which go and come again.

?????: Not sure what the rash is from. Could be insect bites such as mites or bedbugs or it could also be due to a chemical exposure such as a new laundry detergent or some other toiletry item. I would definitely go see your primary care provider and if they cannot diagnose and treat it, then a referral to a dermatologist should help.

Dermatologist: Mosquito bites can become secondarily infected, but the infected skin (cellulitis) wouldn't lie relatively dormant for over 2 weeks untreated without significant consequences. The rashes may be a allergic response to the bites. A dermatologist can advise you best after examining you.

I have mosquito bites on my face since 3 weeks. They now don't itch but they are still red. I put a toopical antibiotic but I want this redness to fade?

Mosquito Bites: Try using otc Cortaid (hydrocortisone) or cortisone 10 which are ant inflammatory. If no improvement in 1-2 weeks visit your dermatologist for a stronger topical medication.

Thought it was a mosquito bite and the redness around it is spreading wait to see doctor in morning or go to ER tonight?

Wait till morning: It does not appear that this is a life-threatening issue and you can wait till the next morning. If there is itching, try antihistamine. If there is breathing issue, go to ER.
