I have noticed a small hard lump of gristle appear over the last two weeks in my fore arm, you can feel it but mot see it, it hurts if i press on it, there is also a very mild one on my stomach, I have had one in my leg for about a year and not thought much of it? I am now quite worried about this.
It can be benign swellings made of fat cells. As u don't have any neural symptoms, u can go for a FNAC from that swellings.
