I"m, not a nurse or doctor, and can't tell much from the x-rays, but I am singularly unimpressed with the care you are recieving.
First of all, Pain relief medicine is for EXACTLY this sort of situation; an injury that will heal, but you need to REST in order for it to heal, so you need to take enough actual pain relief medicine to be able to rest. Thus, only a real pain reliever will do that, and that means codeine. Sorry, but that is the real blessing of this miracle drug; relief from agony. Don't be scared to accept this blessing. Don't try to 'get by' on less. For the first day or two, use it to allow the mind and body to rest. THEN you go to the tylenol pm and ibuprofen.
Secondly, pain to the degree of wanting to vomit (and since he hasn't taken any codeine, he's not feeling nauseous due to that), is trying to tell yo something; DON"T put weight on me!!!!
I think you should request an MRI. The tendons could have been seperated from the attachement points. Such a high degree of pain seems to indicate a soft tissue injury.
Remember, the squeeky wheel gets the grease, apparently more so in your situation.
