Thanks for contacting hcm, Dear jrvilla..
As you said that your skin that got rash
has healed in less than two weeks but has again started showing some red lesions, i would suggest you show it to your doctor. these could be simple skin healing sequelae but it miught on the other hand be a reaction to the tattooing of the road grit that got impregnated into your skin at the time of injury
. In that cae your wound might start to hypertrophy and might get worse. you can however send your pictures in case you feel it would help. You should not wait longer than two weeks after the initial injury.
Feel free to ask any other queries if you have...
