Recommendation on what to do is rest them. What not to do is anything that makes you scream!
Seriously though I bruised centre of my ribs back at end of April same as you they xrayed as for first 24 hours i could barely take a breath and it took god months to go away. Couldn’t sleep for days lying down, I had to sit up on sofa to sleep. The pills would last til about 2/3am and then i’d wake up in excruciating pain. It really is a slow route to recovery for bruised ribs. In fact its only just maybe the last two months that I can breath to my full capacity without hurting at the top of my breath!
So, I smacked myself hard on Relentless 24 and ended up in a&e (after the event and after driven home) with lots of pain in my ribs. X ray confirmed nothing broken, just severe bruising. They have given me co-coda mol & naproxen. Anyone have any recommendations on what to do / not to do? Rode to work and every ridge in the road was a wave of pain. Does #5 take preference or is there a more prescribed route. Walking at speed is now a challenge.
