visible quarter sized lump in calf?

On my lower left calf I noticed a very small lump.. It was so small that you had to push and move your finger around the little lump (smaller than a dime) in order to feel it. I told my mom about it and she told me to keep an eye on it. Well I forgot and this evening I felt my leg and there's now a huge lump that you can now see visually.. It doesn't really hurt.. If you were to push on it very hard it may, however I would rather not hahaha! I tried using a symptom checker and the explanations it gave didn't compare to what I have. I do not currently have insurance so going to the doctor right away for something that may be minor is my last option.. It's now about the size of a quarter and as I said its a visual lump.. No difference in color.. Not red or even pink.. I just need to get any ideas as to what it could be! Thanks!
