Thanks for posting,
Apparently the maneuver( which involves pressing on your abdomen and rib cages) will later on lead to muscular and nerve
pains due to the compression. If the pains are that severe and restricts your daily activities I suggest you take some analgesia/pain killers to relief you. Within a couple of days to a few weeks, you will feel a lot more better. If after taking the medication you still feel pain, just see a primary care
physician for further medical assistance.
Hope this was helpful
