(I really mean the hard part of the lower leg, not the calves).
It’s unaccustomed muscle usage. Nothing to worry about, just build up your training gradually so you acquire strength. Then you won’t feel the muscles working as they will already be strong.
While these muscles hurt, DO go and get some osteopathy / physiotherapy rehabilitation. Go and see a sports specialist, preferably someone who has a track record in rowing and indoor rowing. Get them to help you to release the muscle tension, massage can improve blood flow to the area which promotes healing and also to review your total posture in case there’s a postural reason why your rowing machine has caused this (minor) injury.
I have personally always got great treatment and rapid rehabilitation from osteopaths. Others use phyiotherapists, chiropractors, dry needling specialists and massage therapists. Find one who works for you.
Rules with rowing injuries
- Get them treated FAST
- ONLY use a sports experienced therapist
- Ask the therapist to get you back into training as soon as possible
Remember, medical doctors rarely have sports experience and frequently will recommend rest alone as a way to heal. Rest alone does not heal injuries. Keeping active during your rehab speeds recovery and also ensures you keep some base fitness in the uninjured parts of your body.
