Red spots on the skin, especially after a rash, would indicate that there is an allergic reaction that you might have suffered from. An allergic reaction in the skin that can manifest itself in red spots include Rosacea, cellulitis, insect bites, hives, contact dermatitis, and reactions to medicines or environmental toxins.
Treating allergic reactions in any part of the body requires the use of anti-inflammatory drugs and anti-histamines. This is because the allergic reactions and reactions to infections are almost similar. This fact goes a long way in explaining why allergies exist in the first place. Allergies are a reaction to a common pollutant that is considered a foreign object or pathogen; therefore, the first reaction is for the body to inflame. Inflammation is seen in other parts of the body by the presence of swelling, redness, mucus production and pain – inevitably, because the nerves get depressed with the swelling. The drugs that are used to counter the effect of inflammatory reactions are either, Non-Steroidal Anti-inflammatory Drugs or NSAIDs or steroid-based drugs. Steroid-based drugs tend to shut down the immune system of the area, as is the case in hydrocortisone ointment, or suppress the entire immune system, as is the case in prednisone. The most important part of dealing with skin allergies is to treat it holistically and by eliminating the cause of the allergy – which in the case of Rosacea, for example, is to avoid letting blood proteins from coming in contact with intestinal bacteria.
A home remedy can only focus on mirroring the treatment of the symptoms and that means eliminating the rash. Avoiding the rash in future would require that you try to identify what gave you the rash. Since the allergen is not known, the use of lavender oil, tea tree oil, and aloe vera are some of the treatments that ought to be tried out. Lavender oil should be used if your rash takes the appearance of an insect bite. Tea tree oil, being an antiseptic, should be used when you suspect that the rash could be infected. Aloe vera should be used to seal the wound as a bandage would. It also has mild anti-inflammatory properties so this would help if you faced the problem purely from contact with an allergen. Orally, you should dramatically increase the amount of ginger and feverfew herb that you take, by adding these to tea. These are both very powerful anti-inflammatory herbs as well as analgesics that can be consumed without serious repercussions.
