I got a lymph node on my under arm when I used a perfume... I consulted a derma and used adaplene gel and an antibiotic which cured it... But I got that node swelling back after 7 months on the same spot.. due to sweating I kept hot compress and used that gel and cured it... I keep getting that back when I sweat or wear a tight clothing.. is there any reason for this ?? Can anyone suggest a permanent solution .. ??.. I'm pregnant women in my 6 th month
