how long does the bruising last?
depending on what type of bruising it is. i acquired a small lump from what i believe from hitting a valve the other week and immediately after my shot i rinsed the mark under hot water for a few minutes which allows whatever drug missed to help absorb as much as possible at the time. massaging the spot periodically will also help with this. in this case my mark last 2-3days tops.
other bruises from bigger missed shots like SC, IM etc are prone to stay around longer with the possibility to become an abscess. generally in these cases there is going to be some kind of lump and hardness. again, a hot compress, and massaging will help, not cure it though. vitamine e oils, aloe vera, neosporin, rubbing alcohol etc all help keep the sight sterile.
how long does the hardness last?
this will depend on the severity of the missed shot and generally means you've IM'd your shot. a good idea is to get a marker pen and draw a circle around it and monitor the size and the redness over the next few days. if it grows larger outside the circle its time to seek medical advice ASAP, there's no other advice to be given here. and if the redness continues to get worse and gets more painful in time go to an ER, dont go doing the home draining by sticking a needle in and drawing out the puss or whatever if its an infected abscess.
how long do track marks take to fade away?
this is all speculation, really, case by case dependent. what kind of track marks exactly? like scarred up, inch long marks on your vein? or a simple dot after an injection?
i've had an inch long mark up the crook of my elbow which took a few months to fully heal. i was applying aloe vera, vit e oils, taking vit B supplements and getting plenty of sun. the larger track marks are scarring of the skin which will take a lot longer to come better than just a few single injections over the place. rotate vein sites to avoid this
aloe vera, vitamin e oils, neosporin, rubbing alcohol, there's plenty.any type of skin cream to speed up the healing process?
what type of make up to use if you have a good bit of them on your inner arm and top of your hands?
i'd avoid hitting in the hands altogether like capt heroin said. if you have to though, some kind of concealer would work well. i know my friend has used some concealer his gf uses and it helped cover up his marks well when he didnt need them to be showing. anything remotely close to skin colour. avoid spray tan

i edited out a few unneeded remarks, please keep this on topic, guys
