my lower back hurts when I arch it but relief after a decent arch. Also my ribs tend to rub my anytime I try to build my core or slim down. my tailbone seems to be protruding further than normal. I cant sit up straight I either lean left, right, or forward resting my elbows on my thighs or knees. No tailbone pain but sit ups cause it to rub the skin and either irritate or tear it, it is not polyps it only happens with a repetitive sit up motion leaning left or rite prevents this, so I am stuck with crunches which is even worse on my lower back.
Hello, Welcome to Chat Doctor, The posture of your body during sitting a standing is very important. If you are having severe back problem take rest for some time donor stretch the muscle and make it worse. To relieve pain you can take NSAID for reliving the pain from your treating doctor. For longstanding back pain you need to strengthen up your back muscle by doing particular exercise which increases the muscle strength and tone. I suggest you to take some physiotherapy and follow the exercise for long term benefits. Hope these suggestions will improve your condition.Thank you.
