A few years ago I had a lump rumoved from my right side, by my rib cage. The Doc had a biopsy done and it turned out that it was a precancerous cyst in a nerve cell. I now have three lumps on the insides of my thighs, two on the right, one on the left. The two on the right are small and hard and occasionally discharge like a pimple but they never go away. The one on the left is larger and softer and will get bigger and then smaller. All three are sensitive but not really painful. Could these be schwanoma as well? Any one had anything similar?

To be really sure, you'd need a biopsy.
