Im so sorry to hear that you are having problems. But I had the same thing happen with both my lungs having small clots probably caused by the DVT I developed in my leg after surgery. I had bad pains trying to breath as well and my husband called the hospital and they said to come in to emergency. Glad I did!
I was scared at the time and really worried about what the clots could do to me but after seeing a haematologist a few weeks after getting the clots, she reassured me that they had most likely already dissolved. The Clexane blood thinners injections are a real pain (literally) but I know they are keeping me safe. I'm on number 187 needle tonight (yep, I'm counting) and I'm hoping I can go on tablets, probably warfarin, after my Herceptin treatments finish mid May. Fingers crossed.
You do get used to the needles but hopefully you can go on the tablet form which would be much better. I'm coping well with the needles though so I'm sure whatever treatment they put you on you will too. It's good the clots are small and they probably are already being absorbed by your body.
Remember Karon this is a long road to full recovery and your body has been battered along the way. With good rest and looking after yourself, not doing anything too strenuous for a good while, you'll get through. I did some vacuuming the other day and tore some internal stitches in my tummy suture so it's a very good excuse for me not to do the vacuuming. Hehe.
