I’ve had sore ribs on the right under my arm pits for 5 or 6 weeks, not quite as bad as cracked ribs and it’s not stopping me riding. Now I can’t recall banging them and yesterday the exact same pain started on the left side. Then it suddenly dawned on me that it could be my HR Monitor band maybe digging in where the plastic connectors are, I started wearing it around about 8 weeks ago.

Anyone else ever had this and if so any suggestions for padding the affected area?
