 [ Symptoms ] if i have my undiagnosed hypertension diagnosed it will become a preexisting condition why should i have it diagnosed  in late 20s always around 160 170 lbs at 511 semi active havent had a checkup in over 10 years hypertension has lessened some of what i could do but otherwise i have lived with it just fine plus i have other medical issues that are more intrusive to my quality of life which will never go away if i have hypertension diagnosed then it will become a preexisting condition and will cost me 10s if not 100s of thousands of dollars in added medical costs during my life [ Disease ] well your symptoms certainly warrant a checkup what you are describing could be something as benign non life threatening as a cyst or something more serious the fact you have had pain and swelling in the area plus a fever could point more to an infectious process than to something like cancer but only a physical examination by a medical professional can say for sure and either way this lump seems to need treatment i would suggest you make an appointment with your primary health care provider as soon as possible to get this lump looked at wishing you all the best
