Do you have implants in your feet that are activated from time to time or perhaps continuously, and when stalkers with phones appear, the implant becomes extremely active and the pain is increased? You could have an Active Reader Active Tag (ARAT) system which uses active tags that emit a signal AND are awoken with an interrogator signal from the active reader.
These operate at 433 MHz. If you have a HAM radio, put in 433 MHz and do a scan. If it stops and shows you a signal being transmitted during the time your feet are being activated, you have picked up the signal to the implant. The signals that wake up the implant with an interrogation signal will be in the 433 range. If you see a stalker with a cell phone GPSing you, put on your HAM radio and do a scan and see what frequency you pick up on the signals that cause pain. Be sure and take a picture of your stalker. They may be holding their phone high to identify themselves as your stalker, however, others just have them in their pockets.
433 MHz Ultra High Frequency Active RFID Tags – up to 500 meter read range (1,500 feet) SkyRFID carries a complete line of 433 MHz readers and tags that can be used for many industrial, healthcare, mining, and other tracking and locating applications.
Other implants are going to be in the ranges between 402-405 MHz which you can find the interrogation signals within these ranges on your Ham radio.

RFID systems can be classified by the type of tag and reader. A Passive Reader Active Tag (PRAT) system has a passive reader which only receives radio signals from active tags (battery operated, transmit only). The reception range of a PRAT system reader can be adjusted from 1–2,000 feet (0–600 m), allowing flexibility in applications such as asset protection and supervision.
An Active Reader Passive Tag (ARPT) system has an active reader, which transmits interrogator signals and also receives authentication replies from passive tags.
An Active Reader Active Tag (ARAT) system uses active tags awoken with an interrogator signal from the active reader. A variation of this system could also use a Battery-Assisted Passive (BAP) tag which acts like a passive tag but has a small battery to power the tag’s return reporting signal. [Power can also be generated by piezoelectric technology – from body movement, such as when you put your foot down on the ground. A pressure sensor will gather energy to power the device.]
Fixed readers are set up to create a specific interrogation zone which can be tightly controlled. This allows a highly defined reading area for when tags go in and out of the interrogation zone. Mobile readers may be hand-held or mounted on carts or vehicles.
