Hiccups are involuntary spasms of the lungs associated with esophageal irritations. They are triggered by the phrenic and vagus nerves.
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
Spinal chords
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.

They will not cause major harm to skin but, if they get enough time or temperature they may cause irritation.
The major nerve that serves the head, neck, and shoulder plexus is the spinal accessory nerve (CN XI). It originates in the brainstem and courses through the neck to innervate muscles involved in head turning and shoulder shrugging.

If a mosquito bites you on a scab you will not get blood clots. This bite may cause major irritation but it will not give you blood clots.
