Patient: Have cyst like hard lump under the fold of left butt cheek and leg. It’s hard and about quarter size. Has been there for about 3 weeks it had no pain but a tad sore to touch right now. Since yesterday on the same leg around the top of leg it feels like I ran a mile on it and didn’t do anything strenuous ..tired weak feeling in upper leg and butt cheek and strained. Can these be related and I am prone to cysts doing you think it may just be benign ?
