[|Human|] I have a sub dermal cyst in my right buttocks. I work out twice a week with a personal trainer. It feels like the cyst is being aggravated by the muscles being formed in my buttocks. I am noticing a sensation running down my leg stopping at my ankle. I have an appointment in a week to see a surgeon. I believe it needs to be removed as it is getting hard to the touch. It used to be soft. Can you tell me what is happening? Thank you. Oh I am 67 year old female. beverly
[|AI|]  Hello and welcome to Chat Doctor, Your history suggests that there is a lump in the buttock which was initially soft but has become hard now. Association with a sensation going down up to the ankle is suggestive of a nerve compression or nerve irritation. Lump in buttock can be due to soft tissue lesion or soft tissue tumor. A clinical assessment is required. The the lump is superficial and palpable aspiration cytology of the lesion can be done. Aspiration cytology is an investigation wherein cells are aspirated with the help of a needle, spread on a slide and stained with appropriate stain. This investigation determined the site of the lesion and nature of the lesion. If the lump is deep-seated, imaging may be required e.g. MRI. Consult your primary healthcare provider for clinical assessment and further work up. Thanks and take care Chat Doctor.
