Hello. About 13 years ago I had a lump removed from my abdomen. The hospital lost the results of the tests and told me I would be fine. (I quit going to them after that) I would experience sharp pain where it was for a few years and I was told that it was just nerves growing back. I no longer have health insurance and this lump is still hurting me. It comes and goes. But right now it is giving me extremely sharp pains and it is very tender. What could this be? -- About the lump - it started off as a very small bruise and continued to grow to the size of a tennis ball. It (and fluid) was removed 3 times in the span of a few weeks. It is just under my ribcage on my left side.
