I noticed lump just below collarbone2 mnths ago. End of dec. Quartersized, today looks like a golf ball under my skin hard but usually not painful. I've sweated heavy but mostly at night and sometimes I feel really hot. More tired than usual. Sweating has been going on long before lump thought it was female age thing, I'm a 49 year old smoker. This thing has doubled in size in 5 weeks, can it wait another 5 weeks to be checked?(when I have insurance) Don't know if it's important or not but my urine is really strong and smells. Been drinking lots if water and doesn't seem to help.
