It is playable. As the other said Edge can help. But as an unaugmented mundane let's be real, you will feel quite inferior to all those chrome and magic monsters. Drugs and Edge are nice but the others have access to it as well. And on top of that you want to play Human? Well I won't stop you but don't try to force fight with those superhumans.
Now sadly there isn't really a 'Doctor' build in Shadowrun 5. First Aid/Medic is generally something that a Decker or Mage will take as secondary skills. There is roughly 6 role you can fill and if you are not one of these you won't do much for your team : Muscle, Face, Hacker, Rigger, Infiltration, Magician. WIthout Magic nor Wares you can give up on Magician (obviously), Muscle (you will need to waste half your Edge every fight just to get as much initiative as the others) and Rigger (No Control Rig no jump, sorry chummer). So we are left with Face, Hacker and Infiltration.
A non-augmented/non-magic human face can be surprisingly good. Because you can go EVERYWHERE. Do they have MAD scanner? No problem, Astral Overwatch? Go for it scan me! Your speciality is Disguise and Impersonation. Knowledge skill are always useful for infiltration so don't hesitate to pick a high logic and some Biotech skill to make daddy proud. A - Skills, B - Attributes, C - Resources, D - Metatype, E - Magic. Attribute example : 3 BOD, 4 AGI, 2 REA (with Karma), 2 STR (with Karma), 6 CHA, 5 INT, 5 LOG, 3 WIL. For skills max Acting or Stealth (depending if you prefer Palming or Performance) Skill Group (and the 4 you have left into Biotech) and get Etiquette + Negotiation and don't forget the SSS : See, Sneak, Shoot so Perception, Sneaking and one ranged option. You will even have some leftover for Specialization or to take some other skills. Your money will go into a nice suit (Run & Gun is your friend), car and some gadgets.
For the Hacker I suppose you don't want to go Techno, so Decker it is. There is some nice Ware for Decker but it is possible to use Trodes. Decker need max LOG so you will have good roll for Biotech. Go for A or B - Skills, A or B Resources, C - Attributes. Since you are unaugmented you can often get away with only B Resources. If you go A don't hesitate to get the best Deck on the market and maybe pick a couple of Drones as well.
And the last one is Infiltration. It might looks like you will be behind Wared/Magic Infiltrator but what you can do as an mundane human is be a kind of mixed face. Go for high AGI and CHA, pick some Disguise, Sneaking and Gymnastics and you can just climb into the toilets building, put on your wageslave costum and infiltrate any Corp from the inside. The advantage over a full Face is that you invest less skills into Social and can pick more combat Attributes and be quite good in fight. A - Attributes, B - Skills, C - Resources.
