What Causes Itchy Red Bumps On The Thighs, Arms And Elbows?
an allergic reaction probably
Detailed Answer:
Hello,
this has to be an allergic reaction. Whether it's the detergent or something else is hard to tell. If you only have skin lesions and itchiness (no faintness, shortness of breath, low blood pressure, etc) then you can use an antihistamine pill. Pills work better than local treatments. For the more severe reactions corticosteroids can also be used.
If you have a history of serious allergic reaction in the past or have symptoms besides the skin lesions then you'd better visit a doctor at once. You should also visit a doctor if the symptoms don't get better after the antihistamine.
Watch for side effects and drug interactions. If you have other medical conditions (not mentioned in your text) or take any drug then assessment for potential interactions is recommended first.
I hope it helps!
Kind Regards!
