Re: what does a blood clot feel like
There are several things it could be, and I agree with you. Take him to the ER; don't mess about with something that could become life-threatening at any time. Having said that, it could be costochondritis (an inflammatory condition of the rib cartilege), pneumothorax (air between the lung and the chest wall- can tear the lung membrane and collapse the lung). Anyway, go to the clinic as soon as possible and get it checked out. Sera.
