working in garage a couple days ago got some pressureized solvent under the skin of the left wrist, has become red and tender, with a faint red line from point of injury to just past the elbow joint on the under side of the left arm. will antibiotics help? if so will keflex be a start.
Well if i was you i would go and see your local doctor and ask for some advice.
On the other hand my sister got something like that under her skin befor and the doctor said wash out with warm water.
