I realised I had a lump in one buttock .
Not right in " the crease " as my GP put it today.
Noticed it last week. Note sore to sit on but just a hard lump. Bigger than a pea, smaller than a golf ball.
Made an appointment , but it's went down in size a fair bit since I made it.
GP , who cycles, had a prod at it and has decided that since it's not getting bigger, isn't hot, itchy, red etc that we'll wait and see.
I was hardly on my bike during August and first week of September, then back to daily use and it appeared.
So if it's not gone in a week I've to go back and see about antibiotics.
Meanwhile I can keep cycling.
