Hi
Welcome to the MedHelp forum!
If the itchy red bumps are on your stomach area only, it can be due to contact dermatitis due to a shared garment, a garment kept unused for long, a new dress, etc. It can also be a fungal infection. Apply any OTC antifungal cream with a combination of two or more antifungals (Clotrimazole 1%, Miconazole nitrate 2%, Tolnaftate 1%, ketoconazole, terfibnafine and Butenafine hydrochloride 1%). See if the marks disappear in 10-14 days. If they do, then keep applying for another week. If they do not disappear or worsen, consult a doctor, preferably a skin specialist. Take any anti-allergic tablet or antihistamine to overcome itching. Hope this helps. Take care!
Just to add to this, if it helps. I am in college right now and have not had very much sleep.
