Advice please

My husband has discovered a lump in his left testicle and has also been experiencing a dull, achy pain for some weeks. He visited his GP who referred him for a ultrasound. He received an appointment date for this but then subsequently had this cancelled due to the Coronavirus situation. He was instead advised to contact his GP for another referreal in a few months time once the Coronavirus situation is under control! Obviously he is very concerned,we do have private health insurance but even trying to get a scan through them has proved impossible as the private hospitals available to us are not currently offering ultrasound appointments. Any advice would be greatly received, even trying to speak with our GP is seemingly impossible!! Thanks in advance.
