<s>[INST] Hello!I have a Nickle sized oblong or oval bump growing between my left testicle and thigh... It is very painful especially when I am on my feet. It seems like it is getting worse and the leg of the side that it is on is starting to swell... Any idea what it could be? [/INST] helloThanks for query. The painful bump between thigh and testicle is most likely to be a Staphylococcal infection of hair follicle in a stage of induration (Boil).However, this can be confirmed only on clinical examination by a qualified General Surgeon. Take antibiotics like Doxycycline and anti-inflammatory medicine like Diclofenac twice daily for a week.If it does not subside you may need to consult qualified General surgeon and get it incised and Chat Doctor.  </s>
