hi, the past 6 months i have had a little red mark on my stomach which was squishy up until about 5 weeks ago when i felt that it had gone hard. it is pretty much colourless now and about the size of a grain of rice but it's causing a lot of anxiety and i'm not sure what to do. my mum thinks it is an ingrown hair but cannot be sure although i am still very worried. any advice would be appreciated, thanks :)
