Hi there, I am hoping someone can help me… I have had quite bad pains in my lower ribs and chest, underneath my collar bone all day and would like to know if sleeping on my front and/or side could be the culprit or from doing an hour of strenuous exercise (pilates) the day before (for the first time in weeks i must add!) Could be the culprit of my pain? My body does feel achey all over from the workout, but also my bed is fairly hard/uncomfortable and most nights i sleep on my side, with few problems however i woke up on my front today with the pain. I would really like to know what is the more likely cause and how i can prevent it? Sorry this is long, but thank you in advance for any advice :)
