HiFor the past two weeks I have noticed a large swelling in the lymph nodes in the groin, this has been accompanied by left sided lower back pain and itching in the pubic area. In the past few days the swelling has gotten larger and tonight I noticed a cluster of pus filled spots on the left posterior thigh. I am very curious and a bit concerned as to what this might be. thank you, Kieron
Hi, Cluster of pus filled spots on the left posterior thigh and lymph nodes in groin indicate toward an infective pathology. Chat Doctor.  I suggest you to get it evaluated by your doctor and definitive treatment plan according to that. I do hope that you have found something helpful, and I will be glad to answer any further query.
