Many illnesses share similar symptoms but require different treatments. A medical exam is necessary for an accurate diagnosis, without which appropriate treatment cannot be given.
You should always consult your vet before following any suggestions for medication or treatment you have read about. The wrong treatment could make your rabbit worse or mean your vet is unable to give the correct treatment because of drug interactions. Even non prescription drugs can do harm if given inappropriately.

Urgent Medical Advice: If you need, or think you might need, urgent medical advice you should contact a vet. If it is out of working hours phone your vet's normal number and there should be an answer phone message with instructions on what to do.
Hi. I take it you have not had your rabbit long if he is only 8 weeks old. Have you kept to the exact same diet he was having before you had him or have you made changes?
Is he eating hay? veg? treats? what brand of pellets? Grass?
Sorry for the interrogation!
A change of home is a stressful time for a rabbit. Their digestive system is very delicate so it is always a good idea to keep them on whatever diet they are used to for at least 2 weeks.
Once this time has passed you should be able to make any changes you wish to. Remember a rabbits diet should be 89-90% hay with just a very small amount of pellets (an eggcupful) and a little veg. Any new foods need to be introduced one at a time and starting with a tiny quantity. I would not introduce grass or veg until your rabbit is about 12 weeks old unless of course he has been having them while with mum.
It has been noted by some owners that Excell pellets can cause the problem you are experiencing. Science Selective and Oxbow pellets are popular alternatives. It may be that, once your rabbit has settled and the excel pellets are introduced very slowly and only to a small quantity (an eggcupful) he may be able to tollerate them.
So to sum up, for now keep bun to the exact diet he was on before he came to you and don't make any changes/additions for 2 or 3 weeks.
