I was diagnosed with type2 diabetes after reporting to my doctor with a large abcess on my inner thigh which fully drained. during the draining process, a large area around the drainage was hard..like a clot. it eventually went away and the process repeated itself many times over the next 10 years with the abcess moving closer and closer to my genitals. eventually, my scrotum got one and swelled to the size of a coconut. same thing happened, abcess drained, large area around abcess felt very heard like a clot, and went away after draining. this happened about 5-6 times over a 3 year period. it has now been 2 years since the last one, but the drainage has never really stopped. under my scrotum, from time to time, it bleeds and drains a pinkish fluid with no large abcess, but small lumps are felt under the skin.
