He never had this until I changed his bedding maybe an allergic reactionThat looks sore as at least one bump looks open so he needs to see a vet.
Should I take his bedding out because it didn't start until then have had him for 2 monthsThat does look very sore. Please try to get him an appointment as soon as possible.
Also be aware that guinea pigs aren’t meant to live alone. They need the constant company of their own kind - be it in the same cage or as neighbours. Their interaction goes beyond just having another piggy there.
However much you interact with him, it can’t replace or compare to the company of another piggy. You can’t speak his ‘language’. So please seriously consider getting him a friend. Either another male, preferably the result of boar dating. Or have him neutered and get him a wifey after the six week wait.

I change his bedding every Thursday and yes I did get them from a pet store the old bedding I was using was coloured paper the stuff was not and it's more dustier so I'm just wondering if he's just having an allergic reaction I just taken that bedding out and put fleece blankets in for now but taking him to the vet tomorrow to get his nails trimmedHmmm not sure that would cause any change. When did you change it and when did the sores appear? Did you get him from a pet shop?

I have puppy training pads to absorb the wee wee and I'm not sure I will find out he is a very popular vet hereMake sure that there’s something under the fleece to absorb the wee. Also, sometimes pet shop piggies can come with ‘hidden’ illnesses that may not necessarily show up straight away.
Is the vet experienced with guinea pigs?
I have also put use coconut oil on him and just now I've put a little bit of polysporin on the open soresI have puppy training pads to absorb the wee wee and I'm not sure I will find out he is a very popular vet here

It's an ointment to treat open wounds and it is safe for skinny pigsWhat is polysporin? I wouldn’t use anything at home on him that’s not been prescribed or recommended by your vet.

The reason why that matters is because pet shops routinely give wrong and very damaging advice about guinea pigs, and don't always look after them properly. And if vets aren't experienced with guinea pigs, they can sometimes not do the right thing for your pet. It's the hardest thing about having a guinea pig. This site makes up for all the bad advice out there.It doesn't matter it's recommended for pets and humans for any open sores all pets

And your pigs immune system will be weaker with the stress of living alone.
It's good you've tried a bedding change just in case that was a trigger, you obviously care and your piggy looks very sore, I hope the vet can treat your piggy's skin.
