Sometimes, after intense physical exertion, weight lifting, long walking tours or for no apparent reason, there is a mobile and painless lump under the knee from behind.

- Baker's cyst ;
- hygroma;
- inflammation of the lymph node.

Treatment of cones under the knee from behind
As a rule, all diseases, accompanied by the phenomenon described, are subject to conservative therapy.
In the first few days from the beginning of any of the listed pathologies, it is recommended to take anti-inflammatory drugs of the non-steroid group:
- Diclofenac;
- Movalisa;
- Ketorolac;

If a Baker cyst is detected, further treatment may not be required, as it will dissolve on its own. If the formation increases, the cyst is punctured, during which its contents are sucked off, and steroid solutions are injected into the cavity:

- Amoxyl;
- Amoxicillin.
In rare cases, the examined neoplasms are surgically removed.
