How To Tell The Difference Between A Heat Rash An Allergic Reaction
Rash v Allergies: Heat rash develops when your sweat ducts become blocked and perspiration is trapped under your skin. Symptoms range from superficial blisters to deep, red lumps. Some forms of heat rash can be intensely itchy or cause a prickly feeling. Heat rash usually goes away on its own. Allergic reactions go away with removal of the allergen and return when re-introduced. ...Read moreSee 1 more doctor answer

July i noticed my skin breaking out, heat rash, was going away now seems to be back along with whiteheads on face.Looks bad like allergic reaction, help?
May not be allergy: You don't really describe the original rash and don't mention itching. You also have other issues. Miralax (polyethylene glycol) may cause abdominal pain and diarrhea. Try an anti-histamine such as fexofenadine (allegra) or Loratadine (claritin, alavert). I don't suggest Cetirizine (zyrtec) or Diphenhydramine (benadryl), because they may worsen constipation. If no better in 2 days, see your physician. ...Read more

Not enough info: As to skin rashes, seeing IS believing. I recommend that, if you can't get in to see your own doctor, you go to an urgent care center for evaluation. Alternatively, you could do a Virtual Consult with one of our doctors. You would need to do an audiovisual consult and upload a picture of the rash. The urgency depends on the severity of your symptoms. ...Read more
