Hi Karen

I don't have too many ideas but immediately wonder about any other meds he might be on?

I assume this has been covered by the doctors but will ask anyway - warfarin? pain killers? Particularly those you or Emmett may have bought from the supermarket and may have forgotten such as ibuprofen or diclofenac (Nurofen or Voltaren). This includes even those cream things that you rub on the sore spot.

Any history of ulcers?
