Hello. This is Dr Geyik and I will be assisting you today.
Unfortunately, the options are quite limited if you are going through NHS. NHS is quite overwhelmed at the moment and it can take some time for the referrals to be seen.
However, you can ask your GP to expedite your referral and they could see you earlier.
The other option is to go privately but you would have to pay for this.
If you are happy to see a private doctor, you can have a look at Nuffield Hospital which is a good private hospital and they have branches nationwide.
You can also have a look at the following telemedicine site as they do have various services:
