Pretty sure we have been through the same thing. Switch to a bigger UGL with 100mg/ml primo is all I can suggest. When I did that I still got some of the systemic inflammatory feelings (aches, headaches, pain, fatigue) but no local issues (redness, pain, swelling, hot to touch). Tylenol helps when the systemic issues come up sometimes. I’ve been prescribed antibiotics too and thought I had a full abscess at one time. Doc took a look and said there was nothing there to drain or even treat, and it went away on its own so had nothing to do with infection. I can’t say it’s the same as what you’re dealing with but sounds the same to me
