It does sound like your HMS/HEDS is now effecting your ribs, whether it is slipping ribs syndrome, costochondritis, or just plain old ribs subluxing or dislocating. All these are part of HMS for some people, as they can all be due to lax ligaments.
The dr last night said the pain I was describing was in my ribs, and he asked if I had any fall or injury to them but I dont
This is also typical of HMS - we can injure ourselves in ways that would normally be due to some trauma or injury, and with us it can be instantaneous, with no injury first. It is also typical that a Dr with no specialist knowledge of HMS would insist that there must have been a previous injury, they really don't know any better.
I can't remember whether you have seen an HMS specialist? If you have not it may be a good idea to ask for a referral to one of them. If you already have a diagnosis, do you see a rhuemy who knows about HMS? or just your GP if they are understanding? You need to talk this rib thing over with someone so that you can try to prevent it happening again, and to know how to cope when/if it does happen again, and maybe just to check that nothing else is causing the pain.
