As you were in Glastonbury and in the open, is there any likely chance that you may have got a bug bit on the top of your neck?
With it being soft and tender it even may be a boil forming.
With regard to your ear, it could possibly be because of the very loud noise. They can damage your hearing if the decibels are very high (which no doubt they were).
The pain may and the feeling of fullness in the ear could be from damage in the inner ear due to the noise, or may possibly be congestion in the Eustachian tube or the sinuses.
You do not need to have a cold to suffer from mucus or catarrhal congestion.
If you are concerned and have not much faith in the walk in centre, then it would be better to see your own doctor for a second opinion.
Thanks for your reply.
The tender lump seems to have gone down quite a bit today and I can't see or feel any bug bites. The hard lump is still the same and my jaw aches when I yawn on the same side as it. Still have the shooting head pains too.
I had a wisdom tooth out on the same side a month ago so I was wondering if perhaps that had a slight infection and was causing it.
I do feel quite run down so perhaps it is just an infection of some sort. Just concerned that the small hard lump doesn't seem like a gland to me.
I think you are right, I will maybe wait a couple of days to give the antibiotics time to work then see my own doctor if I am still concerned.
That's a good idea about giving the antibiotics time to work.
I having the wisdom tooth pulled out has changed the alignment of your jaw, that could give you shooting pains in the head.
After you finish the antibiotics and are still having the problem, it may be wise to see your own doctor and also see the dentist to check your jaw alignment and to see if there any other problems with your teeth.
