i have a lump on my inner thigh, I could not see a head to it, but when I pressed it, a lot of water came out, literally squirting like a small water gun. I looked completely clear. I am 40 years old. I recently had another lump similar under my arm pit, but I stuck it with a needle and a lot of pus came out, but this one on my inner thigh is just water. what could this be? 6' tall 265 pounds
