Red itchy bumps on legs can be frustrating, but they are usually nothing to worry about. You may experience bumps from your feet all the way up to the top of your thigh. Most of the time, these bumps are small, raised, and don't burst open. However, in some cases, the bumps can burst and crust over. You may experience itchiness anywhere along this rash on your legs, and it may come and go.
In general, these bumps are not a cause for alarm. Most doctors have seen this type of rash before and know how to diagnose. You may feel the urge to scratch these bumps, but that is not advisable. You can open up the skin and cause an infection by over-scratching. However, if you have already scratched them open, then apply some Neosporin to the site to help prevent infection.
The way to treat itchy red bumps on your legs depends on the cause. The most common way to treat this symptom is by first attempting to remove all allergens. You want to examine your soap choices and determine if you may have been exposed to poison ivy. You can also treat this type of response with anti-histamine drugs, such as Benadryl. That will help cut down the allergic response and decrease the extent of itchiness that you experience. You can also use topical creams to help reduce this itchiness.
If your problem is caused by a virus, then there may not be any treatments available. For instance, with chicken pox, it has to run its course. With shingles, however, you can take an anti-viral medication, such as acyclovir, to help kill off the virus and decrease symptoms. Your doctor must make this determination.
If your problem is caused by vasculitis, then you will need to decipher the underlying cause. It is usually caused by out of control diabetes. If you don't have diabetes, you should probably be examined for it. If you do have diabetes, then you need to control your blood sugar better. Vasculitis is a sign that your blood sugar is out of control and medical intervention is needed.
Red itchy bumps on legs that are caused by bugs also tend to run their course. However, you have to make sure that you remove yourself from the infestation. If you are having outbreaks at night, you may want to consider the possibility that you have bed bugs and call an exterminator. You can use soothing and anti-itch over the counter creams on your legs to help with the itchiness, but for the most part, the bites will resolve on their own.
If you have eczema or psoriasis, you may require medical intervention to help control it. Eczema can heal itself, and it is generally associated with environmental factors. However, psoriasis can be challenging to treat and can result in plaques, or crusty lesions, that form on the skin. You may need an immunosuppressant drug to treat this autoimmune attack on the skin. Your doctor will perform tests on your skin and prescribe strong medications if psoriasis is suspected.
