HELP, this is 4 weeks post surgery. My son is doing very well except for the extreme saliva gland swelling which is very painful and which has limited what he can eat. He is back in the hospital, it was drained once by needle at the Drs. office and when that only worked for a day they admitted him and put in a drain. The drain was not in the right position, it was drained again by needle, did an ultrasound and moved the drain and it is still not working. Severe swelling after he eats to the point that he says it feels like it is dislocating his jaw. The Drs. either don't know what they are doing or have never dealt with this situation before. He will be having radiation and chemo when he heals, we are wondering if one shot of radiation on the saliva gland will stop it working??? Has anyone had similar experiences and can offer some advice.
