Circular rash: May be fungal like ringworm. You can try over the counter anti-fungal medications. Or may be eczema due to dry skin or food /environmental allergies or granuloma annulare which needs steroids, sometimes you can first layer the antifungal and then on top the steroid cream or get a cream that contains both by prescription f/u /w/doc

I have these small red bumps all over my arm, and they are getting worse. Also, can this rash effect the heart? Do rashes affect pain in arm veins?

Impossible to say: How can you expect an answer when one cannot even visualize the rash? See a dermatologist. It is highly unlikely that the rash is associated with cardiac issues. ...Read more

Small, circular spotted rash, was red in colour now turning brown over the last few days, slightly raised, not painful. On top of arm. What is it?

Ring shaped rash: Sounds like this could be ring worm- a fungal infection if the skin. It's quite common esp in hot environments, and if contact with kids. You might want to try Clotrimazole 1% or other topical anti fungal cream for 10 days. If that doesn't wipe it out, better show it to a doc for definitive evaluation and treatment. ...Read more

Arm rash: Rashes are hard for a physician to diagnose without being able to see it. It sounds like it could be a bruise but it could be ring worm, cherry angioma, or many other things. I recommend that you contact HealthTap Prime (and take a picture to upload) or see your physician to give you peace of mind about it. ...Read more

Eczema/dermatitis: A rash that is itchy and scaly is possibly eczema or ringworm (not a real worm, but a name for a fungal infection). Rashes that come and go when it is in contact with something like a watch, rubber band/hair tie, etc can be contact dermatitis, which is due to irritated skin. Eczema and dermatitis can be treated with over the counter hydrocortisone cream. ...Read more

Been experiencing small red rashes and/or lumps on the inside of my left elbow only, vary in size. Usually not itchy, but always in the same spot.?

Been experiencing small red rashes and/or lumps on the inside of my left elbow only, vary in size. Usually not itchy, but always in the same spot.?

Need more info: Dermatology is pretty visual, so it's hard to know what is going on without seeing it. Eczema, psoriasis, and urticaria (hives) can develop around the elbows, though eczema and hives tend to be itchy. Sometimes an irritant or mild allergic contact dermatitis can present in the same place as well. I'd recommend seeing a dermatologist to help solve this one. ...Read more

3 spots on my arm- looks like each has 2-3 small bites in the middle with a red rash around them. They are warm & sorta itchy. What kind of insect?

Need more info.: Probably a venous insect due to the warmth and redness, but it depends on your exposure to outdoor versus indoor environments, when they appeared, where you live, whether you have pet (that can have fleas) or where sitting on a rock in Texas (fire ant bites), before they appeared. Also of interest are how large the bites are, and history of allergy (bee stings, etc.). ...Read more

Red vesicular rash: 18 year old with painful burning vesicles on arm. Get a full medical history and in person physical exam ASAP. You can try a consult in your area as well. If the rash is itchy (pruritic) and painful you need to give more history. The differential is large and it could be anything from zoster to contact dermatitis to chiggers or a reaction to insect bites, bedbugs, or scabies. A picture=1k words. ...Read more

8 mth old baby woke up with rash on cheeks. Small, red, slightly bumpy spots covered her arms and thighs later in the day. No known allergies. Help!

Many causes: But at this age, this is how eczema (atopic dermatitis) often presents itself. Cow's milk and egg are the most likely allergens. However a viral infection or drug reaction may also present in this manner. If there is pus, then impetigo should be ruled out. If the problem persists, see your doctor. ...Read more

Hard to say?: Without more history and seeing it have no idea either? Onset? Is it itchy? Does he have associated symptoms like fever or other illness? Recent cold?
