Rash (Definition)

Most bumps and blotches on a newborn baby are harmless and clear up by themselves. By far the most common skin problem in infants is diaper rash. Diaper rash is an irritation of the skin caused by dampness, urine, or feces. Most babies who wear diapers will have some type of diaper rash.

Left leg really sure. X-rays show no break/chip. Now small red rash/bump on back of thigh above knee. Could this be shingles?

Shingles?: Shingles is a reactivation of the chicken pox virus. Therefore, for it to be shingles, the rash must look like chicken pox. The rash starts out as vesicles, or small sized fluid blisters that eventually scab over. If this is what you see, it could be shingles and you should see a doctor right away to be placed on antiviral medication to stave off post herpetic neuralgia, a very painful condition. ...Read more

Cellulitis: What you are describing may be either cellulitis (which is an infection of the skin), or DVT (clot in the veins), either of these require urgent treatment and you should go to the emergency room as soon as possible.

Is overweigth for 50 lbs can cause leg swelling or enlarge leg w/o pain and redness just little big cmpare to left leg after i was cured of cillulitis?

Is overweigth for 50 lbs can cause leg swelling or enlarge leg w/o pain and redness just little big cmpare to left leg after i was cured of cillulitis?

Maybe: I'm going to guess what you are trying to ask here, b/c your question is all over the place. Weight gain can lead to leg swelling, though one would expect both legs to swell. If you had cellulitis in a leg, it can lead to a long standing swelling problem. Consider use of medical compression hose, 20-30mm hg. Knee high should work. ...Read more

Pretty good: A ddimer, if negative is very accurate. There are many conditions that cause a positive ddimer, but clots nearly always do. If you are really worried, an ultrasound can tell you if there is a clot or not. Without more history it is difficult to say exactly what is going on. Do you have an autoimmune condition? Infection? What did your doc say about it? Ddimer, not perfect, but very good. ...Read more

I have had red round burn looking sores on my left leg , they went away and caused scars.Ms & mvp --they are back an my neuro asked me how i got a burn?

Probably not related: Ms primarily effects the central nervous system and most commonly results in motor dysfunction whereas peripheral sensory neuropathy is more commonly associated with other co editions or disease such as diabetes. Numbness could result in unrecognized injury.If this is a recurring lesion, i would suggest a possible biopsy to exclude other possible problems. ...Read more
